It’s been nearly two decades since Gavin Rossdale’s Bush topped the charts with its debut, Sixteen Stone. Riding the wave of grunge until disbanding quietly in the early aughts, Bush spent the rest of that decade as nothing more than a memory for fans who remembered when the word “alternative” was actually a genre. But if other grunge rockers of the early ’90s, like Soundgarden, can make a comeback, why not Bush? Reformed in 2010, the group got to back to work on its first new release since 2001’s Golden State, this fall’s The Sea Of Memories. Retro fans need not worry, though. Even with a new album and omnipresent, double-take-inducing single all over the radio like it’s 1999, it’s probably safe to say that “Glycerine” and “Comedown” will still make the set list.
