This is a nice compilation of garage psych madness that sounds like it being made by a bunch of devil worshiping hippies during a free form black mass jam; or zonked to the stratosphere Hell's Angels partying in Death Valley with a bunch of reptilians that live inside the hollow earth. In other words this is a fine record and is lots of fun. When I was a little kid and didn't know really anything about rock n roll, this is the kind of sound that I heard (or imagined I heard) coming out of my friends older brothers basement bedroom while we were playing with Hot Wheels. this is the sound of rock n roll that I have been chasing ever since I got into listening to the stuff.
The sound quality is not bad but at times can be a bit murky, but mostly it sounds good. I've heard much, much worse (like those old Stooges bootlegs that sound like they were recorded with a cassette recorder in the trunk of a car in the parking lot of the club they were playing). Ultimate Bonehead is related to the Bonehead Crushers and Bonehead Crunchers compilation also put out by Belter. So pick this up and make your record collection the envy of your neighborhood.
