When Ten Years After's founding member and singer-guitarist Alvin Lee passed away at the age of 68, some of rock and metal's biggest names took the time to memorialize the influential musician.

Lee accomplished a number of great feats in the world of blues-rock, releasing 11 studio albums and seven live recordings during the career of Ten Years After. The blues master also played the original Woodstock Festival in 1969.

Following Lee's death from complications during "routine surgery," rock and metal legends Geezer Butler, Bill Ward, Slash, Joe Satriani, Glenn Hughes + more.

Black Sabbath bassist Geezer Butler wrote, "Shocked and saddened to hear of Alvin Lee passing, one of the true greats and a major influence on Sabbath. The fastest guitar in the west. He was one of the few people that believed in Sabbath when we started out, and he got us our first major London gig, at the Marquee. A true gentleman and lovely bloke. RIP Alvin."
