I'd never heard of Harry Partch, but I followed the Youtube links and... well, I can't say I like art music, but I do hear echoes of Tom Waits in his songs, and I now know where the inspiration for odd atonal music in artsy European 60's movies came from. Interesting, the more you know, etc.
Douglas Adams: I love HHTTG. It is the only book which has made me unable to resist laughing out loud, which was pretty awkward as I read it on the commuter train home each evening, and was an insecure teen. Sadly I think the movie killed the book for later generations, sucks to be them I guess.
