emerson lake and palmer are ground breaking, musicians, although there was a backlash against prog rock, and their supposdly ridiculous shows, that showcase the bands talent, and their individual talents, some people might call their music atonal and might use other such vulgarities, this concert should easily put their doubts to rest. need more convincing, get the album, welcome back my friends to the show that never ends, side 1 second track, i rest my case, welcome to musical liberation.
