Tonight, Twenty One Pilots will do something major for their fans. The duo and rock band Mutemath will team to reimagine five songs, presented in a free "25-minute presentation" video that will result in the songs being downloadable. It goes down at 6 p.m. EST, and is in fact called The Mutemath Sessions.

Watch a teaser straight from Twenty One Pilots:

Several 21P sources say the session will include "Heavydirtysoul," "Ride," "Tear in My Heart," "Lane Boy" and "Heathens," which you can hear a bit in the teaser.
