I just picked this up on I-Tunes. In all, I have to say I really like some of the songs. Others I can take or leave but there is some good guitar work on it. I guess upwards of 30 guitarists worked on it over time but the main credits are for Buckethead and Ron "Bumblefoot" Thal.
In all I recommend it if your not too tight for 10 bucks. I have to admit I picked it up on a flyer assuming I was pissing my ten bucks. Pleasant surprise.
