Some more familiar names from the early 70's:
Uriah Heep
Try Live, Demons and Wizards, the Magician's Birthday
Wishbone Ash
Try Argus and live Dates.
While not as acid drenched as 13th floor elevators, these two are definately very heavy. Uriah Heep Live is an all time classic and Wishbone Ash was one of the first bands to use a dual lead guitar approach which definately inspired Iron Maiden, Priest, etc.
