Even without White Stripe Meg White, Raconteur Brendan Benson or Dead Weather Alison Mosshart, White will deliver. Wouldn't mind some old material though, not just his solo work.

Glittery and fun, the group's new "Something" achieves no better distillation of keyboard-heavy '80s pop than "I Belong in Your Arms," which will 100% appear on the soundtrack to a "Breakfast Club" remake if it ever happens.

This Chicago soul outfit is dynamite on stage, and--cue obligatory bragging rights--won RedEye Rock n' Vote a few years back. Always happy to see big things for our champs!
