U2's Under a Blood Red Sky is an essential for any vinyl enthusiast. By the time of this 1983 live EP, U2 had emerged as the socio-politically conscious, self-determined saviors of rock & roll, their passion, musical power and sheer youthful exuberance making them rock idols to countless young (and some not-so-young) fans. This edition includes high-quality pressings and a detailed recount of the album's influential moments, from recording sessions to its role in shaping musical trends.
