The Truffle

And this week, it's Pink Floyd, performing "Careful With That Axe, Eugene."

Yup, it's the band that would eat all the other proggers for lunch. I'm talking, of course, about Van Der Graaf Generator. This is VDGG performing "Arrow" circa 1975:

Does Focus count as prog? Well, as you can see from the clip below, the guys had a sense of humor--which is why some people would say no, they were not prog. On the other hand, they were European (Dutch to be exact). And they did draw on the European musical tradition, what with their yodeling. And they're on Rhino's "Supernatural Fairy Tales" boxed set, along with...uh...Electric Light Orchestra. (Sorry, I like ELO, but they weren't prog.) Oh heck, let's just call Focus prog. Here they are doing "Hocus Pocus." From the looks of things, that's Gladys Knight introducing them.

A solo turn from Chris Squire of Yes. Looks like he forgot to change out of his bathrobe before heading to the studio. Note Patrick Moraz on keyboards and Bill Bruford on drums. Speaking of Bruford, here he is with King Crimson. Dig the insane percussionist. What is it about Bruford that inspires his bandmates to wear silly clothes? Meanwhile, over in Canterbury, we have the less goofily dressed Soft Machine:

Here's the inimitable Hawkwind performing "Silver Machine," their big, big British hit single, sung by future Motorhead dude Lemmy. And here's Amon Duul II. On the one hand, it's a pretty weird video. On the other hand, it features Renate Knaup on vocals.
