Music On Main--featuring Grand Union

Music on Main — Free Live Music in Downtown Oshkosh
Every Wednesday from June through August, Opera House Square in Downtown Oshkosh comes alive with free live music as part of the Music on Main concert series. Grab a meal or drink from one of the nearby downtown restaurants and settle in for a great evening (or lunchtime show) featuring a diverse lineup of local and regional artists.
The 2026 season runs June 3 through August 26, with most shows kicking off at 5:30 p.m. Three special midday family concerts are also on the schedule — perfect for bringing the kids out for an afternoon of fun. This year's lineup includes blues, jazz, country, brass band, rock, and more, with acts like Reverend Raven with West Side Andy, Water City Jazz Orchestra, Grand Union, and Janet Planet, among many others.
Presented by Alexander & Bishop, with additional support from concert sponsors The Grand, Megan & Peter Lang, Olson Legal, and Generac.
