Boris with Melvins and Boris + Melvins, Mr. Phylzz

Born in Aberdeen, WA, the Melvins are pioneers of the sludge metal genre, influencing grunge icons like Soundgarden and Nirvana's Kurt Cobain. Their experimental sound blends punk and metal, with Buzz Osborne and Dale Crover leading since 1986. Notable works include "Bullhead" and 2017's "A Walk with Love and Death." Collaborations feature Mike Patton and Mike Kunka. Despite major labels and diverse styles, they remain cult favorites known for their heavy riffs and creative experiments.

Japanese sludge/doom rock trio Boris formed in the early ’90s, known for experimental, concept-heavy albums like Absolutego and Flood. They’ve collaborated with Sunn O))) (Altar), Merzbow (Gensho), and Uniform (Bright New Disease).
