I decided to finally take the plunge and explore the world of zappa. So far I've only heard (in discog order): Freak Out, Lumpy Gravy, Uncle Meat, Hot Rats, Weasels ripped My Flesh Waka/Jawaka, Over Night Sensation, and Apostrophe. So far I think I like Uncle Meat, Hot Rats, and Apostrophe the most. Definitely looking forward to checking out more.
