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.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
