Popular Sleep band and Heil sound testing manager   John Hopkins has been reported dead.

John’s death came as a shock as nothing was revealed of what actually caused his sudden death.

Revealing this sad news on Twitter was OM Band through their official Twitter page:

 

Confirming the news also was Lord Dying he said: “So bummed to hear of the passing of John Hopkins. He was the best dude. Wish we could’ve done more tours with ya bud. RIP brother”

John Hopkin is an Illinois native, he mixes FOH for Sleep and also works with High on Fire and the Melvins.

Sleep is an American doom metal/stoner metal power trio from San Jose, California.

The band earned critical and record label attention early in its career. Critic Eduardo Rivadavia describes them as “perhaps the ultimate stoner rock band” and notes they exerted a strong influence on heavy metal in the 1990s.

However, conflict with its record company contributed to Sleep’s breakup by the end of the decade.

The band reformed in 2009 and has played sporadic live dates internationally since. In 2018, Sleep released their comeback album, The Sciences, on Third Man Records, to critical acclaim.

Sleep evolved in the early 1990s from the band Asbestosdeath, which was established by vocalist/bassist Al Cisneros, drummer Chris Hakius, and guitarist Tom Choi. Asbestosdeath expanded to a quartet with the introduction of Matt Pike on guitar, and recorded two singles “Dejection” for Profane Existence and the self-released “Unclean”. Choi departed, and later founded Operator Generator, It Is I, Noothgrush, and Las Vegas’ Black Jetts.

Asbestosdeath recruited Justin Marler as replacement and the band adopted the new name, Sleep.
