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":
