While I think a lot of their material was great (OscarGamblesfros review sums up my opinions as to what was and wasn't perfectly),I do find them somewhat overrated.Plants vocals sound like a bad Janis Joplin imitation,for one thing.My favorite part of the band was the rythm section (Jones & Bonham).No one can say Page isn't a great axeman,but I could name a dozen guitar players who impress me more,and don't even get me started on just how many "Page and Plant" tunes were stolen from black bluesmen!!!!
