In a Facebook post, former bandmate Graham Nash recalled the focus on their sometimes-volatile relationship — Crosby lashed out at him publicly as recently as two years ago in an interview with the Guardian — but said that the "pure joy" of making music with Crosby was what mattered most.

"David was fearless in life and in music," Nash said. "He leaves behind a tremendous void as far as sheer personality and talent in this world. He spoke his mind, his heart, and his passion through his beautiful music and leaves an incredible legacy. These are the things that matter most."

Crosby’s final release, “Live at the Capitol Theater,” came out last month. In an interview with the site ultimateclassicrock.com, he described the performance captured in the recording as “magical.”

Crosby, who was born in Los Angeles, joined the Byrds in 1964, scoring their first hit with Bob Dylan's "Mr. Tambourine Man."

Crosby, Stills & Nash — later known as Crosby, Stills, Nash & Young when joined by musician Neil Young — were founded the following year and released a series of hits with "Marrakesh Express," "Just a Song Before I Go," "Woodstock" and others.

The band's album, "Looking Forward," was released in 1999.

Crosby was inducted to the Rock & Roll Hall of Fame twice — once in 1991 with the Byrds and again six years later with Crosby, Stills & Nash.

In last month's interview, he said that he was no longer touring because of tendonitis in both hands.
