Ulcer. These guys were around in the early to mid 1990's and played blistering hardcore, bordering on grind, with plenty of doses of thrash and power violence thrown in the mix. Ulcer did split records with 90's HC mainstays Capitalist Casualties and Failure Face, which should give you some further clue to their sound. To my ears they share a lot in common with Rhode Islanders Drop Dead, but with more insane vocals - reminiscent of Septic Death or, even more closely, the Unsettled Ep I posted so long ago. This CD collects all of Ulcer's material - an Lp, an Ep and two split 7"ers, along with the aforementioned live set. Enjoy.
