There's a fury at the core of Yoko Ono's 1973 rock opus Approximately Infinite Universe that was not apparent on previously recorded efforts. Ono has always been a master of turning pain and sadness into art, but here, there's a clenched-fist intensity that sets it apart in her deep, unparalleled catalogue. Ono is angry. She proved that one can carry a boundless love for humanity and still be furious - furious at male/female relationships, at war, at your partner. Meanwhile, on a sonic level, Ono ups the ante on the more centered rock-n-roll sounds she approached with 1971's Fly. The album is one of the most traditional-sounding rock chapters in Ono's sprawling catalogue. There are moments here that absolutely rival Jersey legends the E Street Band ever dared tread. Approximately Infinite Universe is an essential and progressive piece of Ono's output, both in the advancements she made as a songwriter/conceptualist, and as a solidified statement of her staunch feminist role within the very male-dominated mainstream rock ghetto of the mid-1970's.
