Alice In Chains picked up on the moodier end of ‘60s and ‘70s rock—Black Sabbath, Deep Purple, and The Doors—while also mixing the intensity and anger of the Stooges and Sex Pistols into their sound. Sludge and metal influences from the Melvins and Slayer hit the chest, resulting in a downtempo, melancholic sound that has only gotten heavier over the years.
