With the Beatles newly digitized, the time is right to revisit the avant-garde icon still best known as John Lennon's widow. Ono's latest remakes the band she and Lennon led in the Seventies, this time with experimental jazz musicians, synth scientists and her son, Sean Lennon, for a survey of the outlying territories Ono has bushwacked for decades. Noise grooves and electro sit alongside Ono's fragile peace prayers and poignant poetic freestyles ("I'm Alive"). At 76, her music remains truly vital: unsettling, touching, funny, undeniable.
