• Recorded less than a year after the release of their full-length debut, 1980's Boy, and before the release of their 1981 effort, October, U2’s May 1981 show at the California Hall in San Francisco illustrated well the explosive passion and energy shown by the group's four members, all of whom were in their very early 20s when this startling performance took place. • While there may be technically more impressive live releases from the Dubliners, few recordings capture the vitality and exuberance that they had as youngsters trying to forge a career before their rise to fame. This is a sound of a band, rooted in punk, on the cusp of finding their own unique voice. • For fans of U2's early material, this show is undeniably a treasure, because the group runs through their entire debut release, save its closer ‘Shadows and Tall Trees.’ It also features many of their non-album numbers, such as ‘11 O'clock Tick Tock’ and ‘Cry.’ Musically, the performance is driven by the Edge's trademark melodic stabs and reverb-soaked melodies, especially apparent on the instrumental unreleased favourite, ‘Things to Make and Do.’ Bono is overflowing with charisma and confidence, which is apparent even in his youth.
