Arcade Fire are currently in Los Angeles preparing for their performance at the Grammys telecast (tomorrow morning for me), where they've been nominated for Album of the Year, Best Alternative Music Album and Best Rock Performance by a group or duo for "Ready to Start."
While in LA, they dropped by the station KROQ and played "Month of May" and "Ready to Start" live on air, acoustically. But you'd never believe that they weren't amplified. Watch the two videos and tell me honestly if you would've guessed that they weren't plugged in if I hadn't told you!
