Legendary Seattle grunge rockers Pearl Jam have left no doubt as to their love for prog rock legends Pink Floyd over the years, performing many of their classic hits at their shows over the years. The band continued that reverence Wednesday night at a show in Porto Alegre, Brazil, with a performance of the Pink Floyd favorite, "Comfortably Numb". Frontman Eddie Vedder has performed the song before, joining Pink Floyd's Roger Waters onstage at a 12-12-12 benefit concert, but the band has never performed the hit before. The Seattle legends eloquently recreated Pink Floyd's signature, haunting sound, and the performance was made almost surreal by a pounding rain falling during the performance.
