A giant of the progressive rock world, Squire helped form the band Yes – which he was part of for nearly 50 years. Squire added a melodic element to his bass playing which proved to be an influence to many prog rock/metal bassists that followed. Known for playing a Rickenbacker 4001 bass, the company came out with a special edition model in honor of Squire, who died in 2015 at age 67 after a bout with leukemia.
