Well yeah, they kinda went awry on the self titled. You want to try some of the early demos, such as 'pterafornication', and 'the span of Quetzalcoatlus'. They kinda sold out and went a bit soft on 'archaeopteryx', and then pretty much went to shit with aforementioned self-titled. They have promised a return to previous great music with the next release, 'the span of Quetzalcoatlus 2: Quetzalcopulation', but I'm not keeping my hopes up. But anyways, if you want a good slice of sludge/grind with some prehistoric drumming interludes, check them out.
