This album has some of the most fascinating,bizarre sound at some points and other songs are flat out boring. Si Senor The Hairy Grill being the masterpiece of the bunch with an organ biuldup to an amazing crescendo of screaming guitars (or is it just screaming?). Dr. Van Steiner, Goldrush, the latin~tinged La Habanera, and to a lesser extent, Oh Yeah, are all fine, and incredibly inventive tunes. Shirley Bassey is great in the Rhythm Devine, but the rest is a tad blah. Still worth it for all the greatness, and was a must buy for me as I used to have it in the 80's and really missed it. Jamming out to Si Senor was worth it all.
Positive
