By the Nineties, Rush had all but abandoned their synthesizers for the Zeppelin-style riffs and prog-pop melodies of their Seventies albums. This one-CD (plus bonus DVD) anthology tracks the band as it drifts from the shimmery, grunge-flavored "Earthshine" to the acoustic-based "Nobody's Hero," a sweet, if clumsy, ode to a dead gay man and an abused woman — with occasional departures like the New Wave-ish "Roll the Bones." One thing that Rush never lost: the comic-book profundity of lyrics such as "They travel in the time of the prophets" ("Dreamline"). Unless you're a Rush loyalist or a member of Coheed and Cambria, you can safely skip Retrospective III.

“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.
