Not yet heavy metal's Homer Simpson, Ozzy Osbourne in 1980 was nonetheless an elder statesman. But on his solo debut, the locomotion of "Crazy Train" proved indelible; explorations of alcoholism ("Suicide Solution") and Satanism ("Mr. Crowley") courted controversy; and the porn- addict rehab "No Bone Movies" matched metal's proggier, punkier younger bands. This remaster (issued simultaneously with 1981's Diary of a Madman) highlights rhythm-section tracks, and stands as a tribute to fallen Randy Rhoads, whose guitar symphonics majestify both the proper album and three bonus live cuts.

“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."
