Roman Castavet makes me think of Red Krayola and Boris covering something from Echo and the Bunnymen's Crocodiles. Woodstock Monster sounds like L7's Pretend We're Dead and Nirvana's Aneurysm holding hands and headbanging at a Hawkwind concert (even weirder, considering this was recorded in '88). And Moon & Milk Bar builds into something resembling one of the Butthole Surfer's old brown-acid instrumentals (In fact, several of their songs display the type of psych-damaged heaviosity that the Flaming Lips burned through on Hear It Is, and both records reference Eddie Cochran's Summertime Blues).
They have at least two more albums, although I haven't had any luck finding anyplace that sells them outside of Japan. If you know where to get them, leave a note in the comments, please.
