Before there was grunge there were a host of bands that would eventually be lumped together as “alternative” who displayed significant metal influences, even if they blended them with funk, modern rock, industrial or other sounds. I cut my teeth as a teenager in the early 90s on a lot of this stuff, so it’s near and dear to my heart:

Jane’s Addiction, “Ocean Size”

Helmet, “Unsung”

Ministry, “N.W.O.”

Therapy? “Teethgrinder”
