About two blocks northwest of Brothers Bar, the austere Humanities Building houses UW-Madisonâ??s School of Music. The building itself stifles the music, officials say. Heating ducts rattle the walls and ceiling during sensitive moments in concerts. The full orchestra violates fire code when it squeezes onto the Mills Concert Hall stage. Windows arenâ??t insulated. Ceilings are peeling. Over the 40-plus years since the school moved into Humanities, about 30 faculty grew to 50. Two hundred students made way for 450. There isnâ??t enough office, storage, practice or performance space.
