Since 1920, the Wisconsin Union has sponsored one or more regular series of concerts by visiting artists of national and international stature. Since 1940, these concerts have taken place in the Union Theater, a 1300-seat hall with comfortable seats and good acoustics. Indeed, it is the best venue in town for solo and chamber-music concerts.
