One of the biggest issues with getting into Zappa is where do you start? Most people only know or associate him with goofy novelty songs, but he has albums that are all over the place in terms of quality and "genre". Sheik Yerbouti is what I imagine most people associate with Zappa in their heads, but then you have Jazz From Hell, Yellow Shark, Civilization Phase III/Lumpy Gravy, Cruising with Ruben & the Jets and Grand Wazoo. All vastly different. Some are purely created on a Synclavier or performed by an orchestra or mostly instrumental. All the posthumous releases do not help with an already bloated catalog.
