Listen to the brand new Unknown Mortal Orchestra song "American Guilt"

What a pleasant surprise this was...

Unknown Mortal Orchestra have released a brand new song called "American Guilt" and it's got one helluva catchy riff.

UMO shared the song on their Facebook page with new tour dates and a message:

"It’s been a minute, friends! This is a new song and I hope you love it the way we loved making it for you in the blazing humidity of Hanoi, Vietnam and a quaking Mexico City. It's called "American Guilt""

More please!
