There are so many great Japanese HC bands with just demos or only comp tracks. You could spend a month or two filtering through just all the MCR and Discrete comps (youtube has a surprising number of them if you don't own them yourself); let alone all the other lesser known labels with great comps. Highly recommended, and fun, listening project. The 90's treasure chest is so deep.
DxRxIx - Dirty Rotten (LP) 1983 - wanted to listen to the EP version, but I only have the LP version - it's too bad they switched the order and added tracks in reissue - "Sad to Be" is such a steamroller way to open.
