The members of OM Trio and Umphrey’s McGee met earlier in their careers. Though Umphrey’s McGee has steadily climbed the jamband ranks, the OM Trio parted ways a few years ago. OM Trio drummer Ilya Stemkovsky spent a short period of time performing with Philadelphia’s Brothers Past, and the members of OM Trio eventually came together for some reunion gigs.

This past Saturday Umphrey’s McGee headlined Philadelphia’s Electric Factory. Stemkovsky attended the show and supplied guest vocals on “Bombtrack” during the band’s second set. Umphrey’s McGee will perform at Brooklyn Bowl tonight. A limited number of tickets will be available at the door.
