Rorschach is probably the quintessential "slept on" hardcore band from the 90s. I realize its not "lost" or forgotten but I've been heavily involved in Hardcore since then and never see Rorschach shirts at shows, and most importantly i dont hear many bands influenced by Rorschach. Pavlovs Dog has one of the hardest intro riffs of all time imo.
Speaking of Raw Nerve, I just spent the last few days sleeping on the RN singer Ralphs floor in Chicago. Not sure if any of you know about his label Not Normal Tapes, but I feel like everyone should. His newer band, The Bug, are good friends of mine and incredible. More spazz out noisy hardcore than what Raw Nerve was but worth everyone's attention.
SQRM - Freak is one of the meanest songs recorded
