OMG, you MUST be kidding!!! The '70's........rock 'hard to come by'?????
Oh son........let's start with Johnny Winter, Edgar Winter, Led Zeppelin, Deep Purple, James Gang, Black Sabbath, UFO, The Scorpions, The Allman Brothers, Pink Floyd, Heart, Lynyrd Skynyrd, Queen, Yes, Kansas, Thin Lizzy, Frank Marino and Mahogany Rush........the list goes on and on and on and on.........
The '70's were AWESOME for rock, but the hype around disco seems to have camouflaged some of the best rock ever recorded. There were two distinct "camps" back then: rockers and those into disco. Three guesses which "camp" I fell into. :)
Most of those I've already got. LOL! :)
