The Grateful Dead’s Bob Weir paid tribute to his band mate Phil Lesh following the death of the bassist Friday.

On social media, the guitarist credited Lesh with introducing him to much of the music that would inform his own playing style, as well as influence the Dead’s improvisational music.

“At the age of seventeen, I listened to the John Coltrane Quartet, focusing on McCoy Tyner’s work, feeding Coltrane harmonic and rhythmic ideas to springboard off of – and I developed an approach to guitar playing based off of it.
