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.

“All Along the Watchtower”

Jimi Hendrix got hold of Bob Dylan's early John Wesley Harding tapes and in late 1967 recorded a version of "All Along the Watchtower" with the Experience in London. Dissatisfied with that first development, Hendrix brought those tapes with him to New York in early 1968 when he began work on Electric Ladyland. Eddie Kramer, Hendrix's engineer at the time, told Rolling Stone that Hendrix "was still looked upon by his basically white audience as the mammoth black guitar hero. There was a constant fight within him to expand himself." Hendrix's successful take on Dylan's work has long been recognized by the songwriter. "I liked Jimi Hendrix's record of this and ever since he died I've been doing it that way," Dylan wrote in the liner notes to his Biograph box set. "Strange how when I sing it, I always feel it's a tribute to him in some kind of way."
