Lurching into an impossibly spastic reggae groove (uh, is that a banjo?), this mutant jam shifts midway into a spooky carnival scene, with Cedric Bixler-Zavala's shivering whispers turning to rabid snarls, sultry croons, and heavy-metal howls. Still hard rock's most fascinating sonic freak-show.

“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.
