https://www.youtube.com/watch?v=Mln0RciE2o0 In his heyday, Robert Plant was one sexy beast. The dude had more charisma and animal magnetism than Prince riding on the shoulders of Burt Reynolds. And it had to escape somehow. The lion's share of it oozed out during the orgasmic breakdown of "Whole Lotta Love." Perhaps the most sexually "suggestive" (and by that I mean aggressively forward) song ever allowed on classic rock radio--to this day!--that surreal slice of Plant's personality was the final release from Jimmy Page's legendary guitar riff. The psychedelic freakout surrounding the lead singer's guttural sex noises only adds to the balls-out explosion of passion that would ultimately help cement Zeppelin's legacy as a one-of-a-kind rock band.
