As part of a plan to demolish the building at 155 North Beacon St. that housed the Sound Museum, life science developer IQHQ agreed to donate the 35,000-square-foot building it owns at 290 North Beacon St. to the city.
A new plan will make rehearsal spaces available in Dorchester for musicians who must vacate the Sound Museum at the end of this month. But the evolving saga has raised questions about whether the city could have done more to preserve a major local music business.
