I particularly like "Imaginary Disease" which is an all instrumental affair released from the vault in 2007. It is Zappa at his finest playing jazz/rock fusion style with a full horn section. The title track, DC Boogie, and Montreal are stand out cuts. Makes you appreciate not only what a great guitat player Zappa was, but also what a keen ear he had for complex arrangements. Unfortunately, this one is getting hard to find and consequently expensive.
