Death Cab For Cutie arrived at the Grammys on Sunday sporting blue ribbons, which they revealed were worn to highlight their new campaign against "Auto-tune abuse in music".
Frontman Ben Gibbard told reporters: "Autotuning is a digital manipulation, a correction of a singer's voice that is affecting literally thousands of singers today and thousands of records that are coming out. So we just want to raise awareness while we're here and try to bring back the blue note… The note that's not so perfectly in pitch and just gives the recording some soul and some kind of real character. It's how people really sing".
