Although often tagged as the poster boy for '90s alt-rock, Billy Corgan's trailblazing work with The Smashing Pumpkins is informed by many musical sources: psychedelia, progressive rock, punk and, most importantly, heavy metal.

His chainsaw guitar sound on I Am One, from 1991's Gish, bears this out. It's a slamming, Sabbath-like slab of unadulterated metal, with a bracing solo that undoubtedly left more than a fair share of GIT shredders agape.

Need more proof? Check out the lacerating Tales Of A Scorched Earth from 1995's Mellon Collie And The Infinite Sadness. Shoe-gazer rock? Uh...don't think so. Hide small children and animals before blasting this volcanic opus.

"It put the punk into metal or the other way around. Essential listening."
