Big Gigantic sat in with Roosevelt Collier’s Colorado Get Down at The Fox Theatre in Boulder, CO last night. The duo—saxophonist Dominic Lalli and drummer Jeremy Salken—joined the group for the show’s second set.

As previously reported, Roosevelt Collier’s Colorado Get Down features Collier, Leftover Salmon’s Andy Thorn and The Motet’s Joey Porter, Garrett Sayers and Dave Watts. The group played its first show last night, and they will continue their run with two gigs at Cervantes Other Side in Denver tonight and tomorrow.
