Country singer/songwriter Charlie Worsham didn't find immediate success after arriving in Nashville in the late aughts — but 15 years later, he couldn't be happier about his luck.

"One of the best gifts I could have ever had was a practice run at all this, where I shared the victories and the losses with this band of brothers," says Worsham, who is referring to his stint playing mandolin in KingBilly, which had a brief reality TV show but didn't set the charts on fire.

Since splitting in 2010, though, Worsham has become a Nashville long-hauler, a respected first-call known for his tasteful guitar and mandolin playing, smooth vocal delivery, and ace songwriting heard on an enviable collection of cuts. In case you need a reminder, visit his Spotify playlist "Sh!t I've Played On," which catalogs his appearances with marquee country stars like Eric Church, Luke Combs, Vince Gill, Kacey Musgraves, Carrie Underwood and Keith Urban.

But while his own albums, 2013's Rubberband and 2017's Beginning of Things, as well as his 2021 Sugarcane EP, have produced hits like "Could It Be" — which peaked at No. 13 on the Country Airplay chart and cracked the Billboard Hot 100 in 2013 — solo success has largely eluded Worsham. 

So, he kept his head down and did what he came to Nashville to do: make great music. He kept his spirits up by rallying friends like Brothers Osborne's John Osborne and The 400 Unit's Sadler Vaden to play his "Every Damn Monday" Nashville gigs celebrating the music of Lynyrd Skynyrd, Prince and others as fundraisers for his Follow Your Heart arts foundation. In 2022, he earned the ACM Award for Acoustic Guitar Player of the Year, and he is currently nominated for Musician of the Year at the 2023 CMA Awards, which will air on Nov. 8.

For his latest release, the five-song EP Compadres, he stacked the deck with five Nashville friends and collaborators — Combs, Lainey Wilson, Dierks Bentley, Elle King and Kip Moore — and the results are bearing fruit. A re-recording of "How I Learned to Pray," originally cut for Rubberband and now featuring Combs, has already eclipsed the original's Spotify streaming figures two-fold while inspiring more than 14,000 TikTok clips.

"When touring went away in 2020 for a minute, I just picked up more and more session work," Worsham says. "It had always been sort of my moonlighting gig that I loved to do, because the goal is always to play more music and that's one of the best ways to do it with the best players around. I started playing on more and more records and driving to those sessions going, Man, it's going to be a great day. But the one thing that can make it better is that this was my record, so thus began Compadres."

With the Jaren Johnson-produced EP in the can, though, Worsham realized Compadres shouldn't be a one-off event. He now intends to revisit the concept between proper albums, and there's no shortage of potential collaborators. All of which begs the question: Who might make those hypothetical sequels?

"One of the first friends I made in town was John Osborne — how do I not cut a song with him and TJ someday?" he says. "The last couple of times I saw Ashley McBryde, we were talking about our love of bluegrass and what side projects might come of that, and how can I not do a song with her at some point? It would be really cool to create a full-circle moment with Eric Church."

Worsham sat with Grammy.com to share the backstories from the five collaborations on Compadres.

"Creekwater Clear" feat. Elle King

The story of "Creekwater Clear" is that hero's journey of where you grow up in what you know is home, [but] you cross that threshold for a bigger world. You come back changed, but you now have this superpower of perspective. And as Elle has firmly planted her roots in country music, I see it as she's just being welcomed home. She's belonged here this whole time.

She's one of two people who came over to the house actually to sing the vocals. I remember she walked through the front door, my wife's there, and I'm sure if you listen closely you can probably hear [our son] Gabe in the background of her singing. But it's a perfect example of what Compadres represents in terms of not just where I am in music right now, but where I am in life — we're doing a lot of living, and Elle's right there with us sharing the joys and the struggles of parenthood and having a young kid, and doing that while traveling the world. Hers is one of my favorite Instagram accounts to see because it's always something fun that combines rock and roll and toddlers.

"Handful of Dust" feat. Lainey Wilson

I had a [co-]write booked with Lainey and I was really excited about it. She can sing, and she's got songs. "Things a Man Oughta Know" — that's one of those moments where the heart and the chart actually intersect, which is a hard thing to do.

The day before, I went for a run and put her record on and just played it on repeat. I started kicking myself on this run, like, How have I not been jamming this record? This reminds me of Rubberband, my first record. Not tooting my own horn or anything, just I know how much time I put into writing that first record and I thought, I can hear the 10,000 hours that went into this. I can hear that this is somebody who knows exactly who they are and exactly where they're from, and they are unapologetic in presenting themselves in an authentic way

So I show up, we walk up to each other, and it was like we were finishing each other's sentences. I'm just going, "Lainey, I spent all day listening to your record. I'm blown away. I love it. I can't believe it reminds me of when I put out my first," and she's going, "When I first moved to town in my camper and Rubberband came out, it had this effect on me, too." You just sometimes never know when you're in the middle of something, the impact it has on other people. 

I remember the first No. 1 I ever played on was Eric Church's "Like Jesus Does [from 2013's Chief]. But the record that moved me to town was Eric's [2006 debut album] Sinners Like Me. He didn't know me when that record came out, but then I got to know him later and tell him that part of my story and how his story inspired mine. 

"How I Learned To Pray" feat. Luke Combs

I love to call it coinci-God, but first chance I had to really get to know Luke was down in Key West to write for what was going to be a bluegrass record that I'm crossing my fingers still gets made.

I gave him a head's up when I got there. I was like, "Man, I don't want to be rude, but there is one phone call that might come that I'm going to have to take." My wife Kristen and I were expecting our son Gabe at the time, and it was that point where we had told a handful of family members but we had yet to tell the bigger world, and we were waiting for the doctor to call to say whether we'd have a boy or a girl. He totally got it — at that point, I'm sure he and [his wife] Nicole were about to head down that same road, too, and thinking about starting a family. 

[But] it wasn't while I was down there, it was on the flight home. I was on a layover in Atlanta and I wrote down the gate somewhere, I think it's A29, and my wife calls me: "I got the news, you want to wait until you get home?" It's like, "Baby, you know me, I can't wait." She tells me, and I'm bawling. The first person I text is Luke, and it wasn't much later they were expecting their first. Nothing teaches you how to pray like having a kid, so that song chose itself for us. And to this day, it's actually the highest-streaming song I've ever put out, and I never saw that coming.

"Kiss Like You Dance" feat. Kip Moore

The fall of 2014 was not my happiest season. I had a lot of stuff between the ears I was trying to figure out at that time. I was on tour with Kip, and he's a really perceptive dude. I think he knew I was struggling, and he made a point to look out for me that whole tour. And he just never quit calling and texting since that tour.

He had come to a gig I was playing at Station Inn [in Nashville], trying out new songs just for the heck of it. Kip was probably leaving for bus call later that night, so he came to the gig and we were catching up. I played that song, and later that night he texted me the universal signal for, Hey, you might have a hit on your hands, which is, "Hey man, are you going to cut that 'Kiss Like You Dance' song?" And I said, "I am now." 

But it was going to be a while until I could record, so when Compadres started to form as a concept, I thought, How cool would it be if we could both cut this song? We're both a little older and wiser, and we have to pick our nights to go crazy and wild. We made a great video for it, which actually has a great cameo from one of my longest-standing compadres, John Osborne, but we're drinking sweet tea that looks like whisky in the video. 

On the rare chance I am going to go have an all-nighter, I want Kip to be there, because the last real great [one] I remember was on tour with him in 2014. Somehow my bus ended up [being] the party bus. We had two nights in Chicago, and I think we had 30 people on a bus designed for 12. Let's just say I had to pay the cleaning fee for that.

"Things I Can't Control" feat. Dierks Bentley

At this point I've been spending the last couple of summers with Dierks, plus one of my funniest studio stories ever was from a Dierks session for Riser [in 2014]. To this day, I can't remember for sure if I'm playing mandolin on "Drunk on a Plane" or not. 

Back when he was making that record, I was doing a string of dates with Vince Gill in his band, and Vince had a gig on a Sunday night in Milwaukee, and Dierks's session was on Monday. I thought, Well, if I can get an early flight in, I'll make the session. I wake up probably 3 in the morning. I get to the airport, get on the plane to Nashville, rest my eyes, fall asleep. I wake up in a panic because the plane isn't moving and it turns out there was a snow delay, and so I missed that day of the session with Dierks. Thankfully, he kept calling me back.

I don't remember if I overdubbed the mandolin after the fact, but now I play it in the show [as part of Dierks' band] and he gives me a chance to shine every night. He's like my older brother in country [music], and I continue to learn from him and be reminded of how important it is to have fun, and how important it is to treat people well and share your spotlight.
