Sleigh Bells - Infinity Guitars, taken from the album Treats.

Music videos were shot for the songs "Infinity Guitars" and "Rill Rill".

"Infinity Guitars" was also used in commercials for Windows Phone.

I was hearing "Infinity Guitars," one of about ten Sleigh Bells songs in existence, and watching their second show ever.

"On a song like "Infinity Guitars", obviously the delivery is going to be much more aggressive and menacing while a song like "Rill Rill", you are occupying a much different state of mind when you're delivering those vocals."
