Some amazing Japanese psych-rock, released on Atlantic records in 1971. Touches of Black Sabbath and Led Zeppelin. This record is HEAVY, and seemingly ahead of its time. Original copies of this on vinyl still go for a good amount of money on eBay. They've since reunited, and released a new record in 2008. It is a vast departure from their earlier sound (the stuff on their official Myspace page doesn't even touch what they were doing years ago). As of right now, this album is not available digitally, and is only available as an import, but you should really check it out. It's pretty incredible.
