AMG Review of Under a Blood Red Sky

Stephen Thomas Erlewine
All Music Guide

War turned U2 into arena rock stars, and the EP Under a Blood Red Sky captures the band on its supporting tour as the bandmembers adjusted to their larger audiences. Unsurprisingly for a band that always favored the grand statement, the group flourished in such a setting, as this mini-EP attests. Comprised of material recorded in America and Germany, Under a Blood Red Sky draws equally from the band's first three albums, and these live versions, while less textured, are considerably tougher than their studio counterparts and illustrate quite effectively why U2 were considered one of the best, most exhilarating live bands of the '80s.
