Hey, I know they started in the '60's, but Steppenwolf did some great work in the '70's as well. They are NOT to be forgotten.
Magic Carpet Ride, Born to be Wild, and my personal favorite, The Pusher.
I thought 30 Days in the Hole, Stone Cold Fever, was off Smokin? I don't know. I just have the Greatest Hits, with Stone Cold Fever, 30 Days, Doctor, C'Mon Everybody, etc.
