Speaking of Frank Zappa, there seems to be a recent trend for many an orchestra to be playing his compositions lately. You have to understand this though; the guy fought for most of his life to have his 'serious' music to be played by a 'real' orchestra. In his autobiography he talked about how symphony orchestras only play music by dead composers because of a myriad of reason not excluding they didn't have to worry about paying royalties. Well, call it a self fulfilling prophecy. Now, almost 17 years since his death, you can go just about anywhere in the world and hear dead-man Zappa's 'serious' music being by just about anybody. Heck, even the LA Philharmonic put on a performance of pieces from Yellow Shark last night. Seems to be the way, the good composers are never fully appreciated until they croak. Poor Frank.

EDIT: I found a review of last night's concert. Sounds like lots of fun. Read all about it.
