Last nightshocked and awed fans in Philadelphia by opening up the evening’s second set with a spot-on combination of their own “Moonsockets” and “First Tube” by Phish. Sound Tribe came out of the gates with the Phish instrumental and weaved “First Tube” into “Moonsockets.” Eventually the band made a return to “First Tube” before finishing “Moonsockets.”

Our friends at Endless Boundaries have pointed out stellar video of the sequence thanks to stealthvids9:
