The prog bass genius died at 67. His music will live forever. Hear it right here.

Chris Squire, co-founder of progressive rock powerhouse Yes and blazing deity to worshippers of bass guitar, departed this mortal plane on June 28, 2015. He had been battling leukemia.

Squire is the only Yes member to play on all 21 of the group’s studio albums, from 1969’s self-titled debut to 2014’s Heaven and Earth. While frequently overshadowed in the public consciousness by frontman Jon Anderson, guitarist Steve Howe, keyboard player Rick Wakeman, and multifaceted Trevors Horn and Rabin, Squire built the cosmically solid foundation up from which Yes arose and it was his divine thunder that always powered the engines.

Yes’s official statement on the loss of this giant reads: “It’s with the heaviest of hearts and unbearable sadness that we must inform you of the passing of our dear friend and Yes co-founder, Chris Squire. Chris peacefully passed away last night in Phoenix, Arizona, in the arms of his loving wife Scotty.”

The London-born instrumental genius’s mastery of the Rickenbacker 4001 bass prompted the guitar company to produce a Chris Squire signature line of models throughout the 1990s, the 4001CS.
