Live in Philadelphia clearly illustrates the power of Yes music. Recorded in 1979, this concert vivdly chronicles the band's middle era, showing the fragile balance of individual personality, visionary writing, telepathic interaction and brilliant instrumentation that define the timeless music of Yes. Songs: Siberian Khatru, Circus of Heaven, Starship Trooper, The Ancient [excerpt], Your Move/I've Seen All Good People, Roundabout.
