They'd been on ice since 2015, yet the death of David Crosby in 2023 forever broke up one of the greatest supergroups we'll ever know.

Which means Crosby, Stills & Nash's five-decade career is now capped; there's no reunion without that essential, democratic triangle. (Or quadrangle, when Neil Young was involved.) "This group is like juggling four bottles of nitroglycerine," Crosby once quipped. Replied Stephen Stills, "Yeah — if you drop one, everything goes up in smoke."

Looking back on that strange, turbulent, transcendent career, one fact leaps out: there's no better entryway to the group than their 1969 debut, Crosby, Stills & Nash, which turns 55 this year. Not even its gorgeous 1970 follow-up, Déjà Vu — which featured a few songs with one singer and not the others — their sublimation was about to blow apart, leaving shards to fitfully reassemble through the years. (The Stills-Young Band, anyone? How about the Crosby-Nash gigs?)

Pull out your dusty old LP of Crosby Stills & Nash, and look in the eyes of the three artists sitting on a beat-up couch in their s—kickers. The drugs weren't yet unmanageable; any real drama was years, or decades away. Do they see their infamous 1974 "doom tour"? The album cover with hot dogs on the moon? That discordant, Crosby-sabotaged "Silent Night" in front of the Obamas (which happened to be the trio's last public performance)?

At the time of their debut, the three radiated unity, harmony and boundless promise — and classic Crosby, Stills & Nash cuts like "Suite: Judy Blue Eyes" bottled it for our enjoyment forever. Here are five things you may not know about this bona fide folk-rock classic.

There Was Panic Over The Cover Photo

As silly as it seems today — nobody's going to visually mistake Crosby for Stills, or Stills for Nash — that the three were photographed out of order prompted a brief fire alarm.

"We were panicked about it: 'How could you have Crosby's name over Graham Nash?'" Ron Stone of the Geffen-Roberts company recalled in David Browne's indispensable book Crosby, Stills, Nash And Young: The Wild, Definitive Saga Of Rock's Definitive Supergroup. (The explanation: it was still in flux whether they were going to be "Stills, Crosby & Nash" instead.)

The trio actually returned to the site of the photograph to reshoot the cover, but by that time, that decrepit old house on Palm Avenue in West Hollywood had been torn down. (It's a parking lot today, in case you'd like to drag a sofa out there.)

It Could Have Been A Double Album

At one point during Crosby, Stills & Nash's gestation, the idea was floated to render it a double album — one acoustic, one electric.

"Stephen was pushing them to do a rock-and-roll record instead of a folk album because he was the electric guy," session drummer Dallas Taylor said, according to Browne's book. "He wanted to play." (Back in the Buffalo Springfield, Stills and Young would engage in string-popping guitar duels on songs like "Bluebird," foreshadowing Young's impending electric workouts with Crazy Horse.)

Happily, the finished product blended both the band's electric and acoustic impulses; rockers like "Long Time Gone" happily snuggled up to acoustic meditations like "Guinnevere" sans friction.

Famous Friends Were Soaking Up The Sessions

As Browne notes, there was a "no outsiders decree" as this exciting triangulation of Buffalo Springfield, Hollies and Byrds members was secretly forged.

But rock royalty was in and out: at one point, Atlantic Records co-founder Ahmet Ertegun rolled up in a limo with an "eerily quiet" Phil Spector. Joni Mitchell, Cass Elliott, and Judy Collins also turned up — and, yes, Judy Collins, Stills' recent ex, was the namesake for the epochal "Suite: Judy Blue Eyes."

"It started out as a long narrative poem about my relationship with Judy Collins," Stills said in 1991. "It poured out of me over many months and filled several notebooks." (The "Thursdays and Saturdays" line refers to her therapy visits. "Stephen didn't like therapy and New York," Collins said in the book, "and I was in both.")

"Long Time Gone" Almost Didn't Make It On The Album

Crosby's probing rocker "Long Time Gone" meant a lot to him. He'd less written than channeled it from the ether, immediately after the assassination of Robert F. Kennedy.

"It wasn't just about Bobby," he told Browne in the book. "He was the penultimate trigger. We lost John Kennedy and Martin Luther King, and then we lost Bobby. It was discouraging, to say the least. The song was very organic. I didn't plan it. It just came out that way."

It was always considered for Crosby, Stills & Nash, but it was proving hard to capture it in the studio. It might have died on the vine had Stills not sent Crosby and Nash home so he could work on the arrangement — which took an all-nighter to get right.

When he played the others his new arrangement, an exhilarated Crosby tossed back wine, and dove into the song "with a new, deeper tone," as Browne puts it — "almost as if he were underwater tone, almost as if he were underwater and struggling for air."

Ertegun Boosted The Voices — And Thank Goodness He Did

For all the prodigious, multilayered talent in Crosby, Stills & Nash, it's their voices that were at the forefront of their art — and should have always been.

However, the original mix had their voices relatively lower in the mix; Ertegun, correctly perceiving that their voices were the main attraction, ordered a remix, and thank goodness he did. The band initially pushed back, but as Stills admitted, "Ahmet signs our paychecks." As they say, the rest is history.
