This is truly some of the best Japanese HC I've ever listened to. Different to all the dis- type bands you might think of... and for once, that isn't a criticism. They released an album and an EP back in the late 80's early 90's and then some bright spark decided to compile it. Kudos!
Normally I am not that big a fan of HC compilations/discographies as I prefer 45rpm 12"s and 7" - too long and I just get bored. Not here. Not a dud song. Enjoy
