Michael Ofiesh — better known as “O.M.B.” — is a Northern California musician known for turning any room into a singalong. Armed with an acoustic guitar, harmonica, and an endless catalog of songs, he takes live requests on the spot — from James Taylor and John Denver to Morgan Wallen and Duran Duran — with no setlist, tablet, or cheat sheet in sight. Raised in San Francisco and performing across Northern California, O.M.B. brings an energetic, crowd-driven style focused on keeping people singing, dancing, and fully engaged all night long.
