Widespread Panic and Warren Haynes joined forces at the Ride Festival in Telluride, CO last night, as both Panic and Gov’t Mule were headlining the festival event.

Haynes came out for the last two songs of the set, joining in for WSP’s “Blackout Blues” and the final number, a cover of Blind Faith’s “Can’t Find My Way Home”. You can watch fan-shot video of “Blackout Blues” below:
