David Crosby was an influential American singer-songwriter and guitarist, best known as a founding member of two of the most iconic folk-rock groups of the 1960s and 1970s: The Byrds and Crosby, Stills, Nash & Young (CSNY). Born on August 14, 1941, in Los Angeles, California, Crosby grew up surrounded by music and film, as his father was the Oscar-winning cinematographer Floyd Crosby. He began his musical career in the early 1960s, eventually joining The Byrds, where his harmonizing vocals and songwriting talents helped define the band’s signature sound on hits like "Turn! Turn! Turn!" and "Eight Miles High." His tenure with The Byrds was marked by creative successes but also by tensions, leading to his departure from the band in 1967.

After leaving The Byrds, Crosby formed Crosby, Stills & Nash (CSN) with Stephen Stills and Graham Nash in 1968, later joined by Neil Young to form CSNY. The group became renowned for their intricate vocal harmonies, politically charged lyrics, and blend of rock, folk, and country influences. Their debut album, *Crosby, Stills & Nash* (1969), was a commercial success, featuring hits like "Suite: Judy Blue Eyes" and "Marrakesh Express." CSNY's performance at Woodstock and their follow-up album, *Déjà Vu* (1970), solidified their place in rock history, with Crosby contributing notable songs such as "Almost Cut My Hair" and "Déjà Vu." Despite their success, the group’s career was often turbulent, marked by personal conflicts and drug-related issues, yet their music has remained influential for decades.

David Crosby’s solo career also showcased his distinctive songwriting and experimental spirit, beginning with his critically acclaimed debut solo album, *If I Could Only Remember My Name* (1971). Known for its lush harmonies and meditative quality, the album featured collaborations with members of The Grateful Dead, Jefferson Airplane, and Joni Mitchell. Over the years, Crosby continued to release solo work and collaborate with various artists, maintaining a presence in the music industry despite personal struggles, including battles with addiction and health problems, which included a liver transplant in 1994.

Crosby’s later years were marked by a creative resurgence, releasing several solo albums in the 2010s and 2020s, including *Croz* (2014) and *For Free* (2021), which were praised for their introspective lyrics and sophisticated musicianship. He remained an outspoken figure, often sharing his thoughts on politics, music, and life through social media, where he connected with a new generation of fans. David Crosby passed away on January 18, 2023, but his legacy endures through his profound contributions to rock music, his distinctive voice, and his role in shaping the sound of an era. As a trailblazer of folk-rock and an architect of some of the most enduring music of the 20th century, Crosby’s influence continues to resonate with listeners around the world.
