What artist and or album would you recommend that is along the lines of Led Zeppelin
My suggestion is a focus on the time frame that includes Led Zeppelin. There are so many bands to pick from during that time & the tangents you can take off on from there. For example, lets say you get interested in Deep Purple. You find out about this fellow named Tommy Bolin who played in James Gang & then check them out & find out about Joe Walsh.
It's pretty interesting how so many bands, styles & musicians are intertwined.
