After making a surprise appearance with Khruangbin at the first day of Virginia’s LOCKN’ Festival last night, Trey Anastasio has released a new studio track, “Sunset Days.”

The solo acoustic cut appears in the recent documentary on Anastasio, Between Me and My Mind, during the film’s closing scene. Anastasio debuted the number during his acoustic run in December 2018, which remains the only time the song has been played live.

Listen to “Sunset Days” below. Anastasio returns to the LOCKN’ stage this evening for a two-set performance with his solo band, which will feature a full set with guitarist Derek Trucks. A livestream is available via The Relix Channel.
