Graham Nash pays tribute to late collaborator David Crosby

Graham Nash has written a tribute post to his late musical collaborator David Crosby.

After the Crosby, Stills & Nash singer was revealed to have died on Thursday, his bandmate took to Instagram to pay tribute to the late musician.

"It is with a deep and profound sadness that I learned that my friend David Crosby has passed. I know people tend to focus on how volatile our relationship has been at times, but what has always mattered to David and me more than anything was the pure joy of the music we created together, the sound we discovered with one another, and the deep friendship we shared over all these many long years," Nash wrote. "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 continued, "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."

Their bandmate Stephen Stills also issued a statement on Crosby's death on Twitter.

"I read a quote in this morning's paper attributed to composer Gustav Mahler that stopped me for a moment: 'Death has, on placid cat's paws, entered the room.' I shoulda known something was up," he wrote. "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.

"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.”

Crosby was 81. His cause of death has not been disclosed.
