For a guy with soul, you sure know how to pick good 70s rock.While more of a 70's soul music fan I can still dig some of the great classic rock of that era. To do that you look no further than Led Zeppelin who were the unquestionable leaders of this genre. My fav album of theirs is Physical Graffiti, although Zeppelin IV is regarded as their crowning achievement. Here's my fav song from Physical Graffiti (11 minutes of pristine bluesy rock n roll)
