Forgotten heavy bands from late 60's to early 70's

Sir Lord Baltimore - Currently I'm re-reading Bill Graham's autobiography (No, not THAT Bill Graham!). A tremendous book that, without trying to, explains very clearly much of what's wrong with the American music industry today, but I digress. Here's a tale about Sir Lord Baltimore I just read last night: "Dee Anthony had a group called SLB booked into the Fillmore East. They were so awful. As we were moving their equipment, we found a book on how to play guitar on the gtr players amplifier. For the rest of the weekend, we kept asking him what page he was on".

So many bands sadly, after Led Zepplin, they are all a distant second!

Some of my favorites from the era have already been mentioned, but I'll reiterate...

Patto (first album) The first track "The Man" is golden...

Budgie - "Squawk", "Bandolier" and "If I were Brittania, I'd Waive the Rules" are my favorites.

Crack the Sky - First album - S/T, "Safety in Numbers" and "White Music" - Not as heavy. Prog-ish. Excellent.

Hah!! This thread is almost 10 years old! Cool to see mentions of Patto (I like Boxer, too), Budgie, and great art-rock band Crack the Sky. 

Attila. The first band of some guy named Billy Joel. You can thank me later.
