Billy Ray Cyrus

Diplo, Rico Nasty, Ha Ha Davis, and YoungKio also appear.

Plus, Diplo has thrown his own name on a remix of the viral chart-topper.

From Gin Blossoms to St. Vincent, these are the SXSW sets we’d time-travel back to see.

Cyrus + Snot + Hole = Daughtry. Class is in session, kids, leave your brain at home.
