I've watched loads of youtube videos of this guy and I have to say he's pretty damn awesome

I keep expecting him to burst out into some Jazz interpretation of everything what with his appearance How does he get away with it at classical concerts? He obviously doesn't give a **** what anyone thinks (maybe that's what I like about him)

Very interesting man. Shame he is no longer alive.

I hadn't looked him up yet, so that's quite sad.... He definitely looked like a character. I'll have to see what sort of biography details are up about him on Wikipedia and the like.

EDIT:
"Although most famous for his Beethoven interpretations, Friedrich Gulda also performed the music of J.S. Bach, Mozart, Schubert, Chopin, Debussy and Ravel. From the 1950's on he cultivated an interest in jazz, writing several songs and instrumental pieces himself and combining jazz and classical music in his concerts at times."

Looking at some of the other interesting bits mentioned, I might see if there's a Biography/Autobiography around, that should be a good read

There is an interesting DVD about him:

So What?! A Portrait of Friedrich Gulda

I'd prefer a book but I'll take a look at the DVD Cheers!
