In front of distant lighting and thousands of fans, Phish opened the first set with "Wolfman's Brother" and played a Ween cover, "Roses Are Free," for the first time in 136 shows. The band established somewhat of a bluegrass theme with a cover of Hot Rize's "Nellie Kane," and ended the first set with fan-favorite "Fluffhead."
The second set kicked off with a rocking "Carini" that also featured a tease of "Dueling Banjos" and jam into the Phish classic "You Enjoy Myself." Phish encored with "Stash" and capped off the bluegrass-y night with the Osborne Brothers' classic "Rocky Top."
Phish will continue its Boulder run at Folsom Field on July 4 and 5. See photos from the opening show below:
