The crowds at the Nineties reunion party keep growing. (Hey, Sponge, we're saving you a chair next to Seven Mary Three!) But who expected Bush to show up in such buff shape? These guys were always underrated - and their name was one of history's worst bad-timing moves. But the quartet's first record in a decade is a surprisingly vital viva-la-grunge manifesto. Gavin Rossdale sounds about a thousand times perkier than he did on his 2008 Auto-Tune quagmire, Wanderlust, growling chest-beaters like "All My Life" as if he's got something to prove. And judging by "She's a Stallion," Gwen Stefani should be proud.

Listen to "All My Life":

“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.
