Neil Young and David Crosby (L-R) perform on Day 2 of the 27th Annual Bridge School Benefit concert at Shoreline Amphitheatre on October 27, 2013 in Mountain View, California.

“David is gone, but his music lives on,” Young, 77, wrote on hisNeil Young Archives website. “The soul of CSNY, David’s voice and energy were at the heart of our band. His great songs stood for what we believed in and it was always fun and exciting when we got to play together.”

“‘Almost Cut My Hair’ ‘Dejavu’, and so many other great songs he wrote were wonderful to jam on and Stills and I had a blast as he kept us going on and on,” Young continued. “His singing with Graham was so memorable, their duo spot a highlight of so many of our shows.”

Rock and Roll Hall of Fame member David Crosby, founder of The Byrds and Crosby, Stills and Nash, performs onstage during the One 805 Kick Ash Bash benefiting First Responders at Bella Vista Ranch & Polo Club on February 25, 2018 in Carpinteria, California.

“I read a quote in this morning’s paper attributed to compose Gustav Mahler that stopped me for a moment: ‘Death has, on placid cat’s paws, entered the room.’ I shoulda known something was up.David and I butted heads a lot over time, but they were mostly glancing blows, yet still left us numb skulls. I was happy to be at peace with him,” Stills said. “He was without question a giant of a musician, and his harmonic sensibilities were nothing short of genius. The glue that held us together as our vocals soared, like Icarus, towards the sun. I am deeply saddened at his passing and shall miss him beyond measure.”

“David was fearless in life and in music. 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. My heart is truly with his wife, Jan, his son, Django, and all of the people he has touched in this world.
