The Insanitizers were nice enough to send me Guitar Fun well in advance of its release date and said something about having time to take it all in. They weren't kidding. There's 23 tracks here with musical styling spanning straight ahead surf, Joe Meekish instrumentals, rautalanka, a harpsichord tune (I realize it's probably not actually a harpsichord), and... man, I don't know what. True to their name, it does sometimes feel like you're going slightly insane.
