Rock icon Ted Leo and Hollywood Handbook's Hayes Davenport join the final Supergroup of the season to write an unearthly song inspired by a conspiracy theory.

A.P. Bio's Mary Sohn and rapper Big Dipper join Tawny & Alex this week to write a sex positive summer bop about nuance.

This week's super-sized Supergroup features musician Eric Slick (Dr. Dog, Lithuania), actor Kristian Bruun (Orphan Black, Carter), and rapper-comedian-multi-hyphenate Open Mike Eagle. Together with Alex and Tawny, the band writes a soulful song about feeling like an outsider.
