Just a couple of weeks ahead of possibly the most anticipated festival of the summer, LOCKN’ released pro-footage from their vault of some legendary performances including that time that Trey sat in with Furthur in 2013.

The pristine audio and video footage gives a preview of what was to come a couple of summer laters when Grateful Dead celebrated their 50th anniversary with Trey in Santa Clara and Chicago. While Trey is a little contained, the band sounds tight and delivers a stellar Scar>Fire.

Trey came out halfway through Further’s set to play and capped off the epic set with this Scar > Fire.

Here is the setlist thanks to setlist.fm:
