Actually, the Carr Center folks have been using the old Harmonie Club building and putting on shows there for a few years now. Despite the hotel plans, it looks like they will be continuing on in that building this fall and winter too.
Their website shows several art shows, plays, operas, etc. there beginning this month. And starting in October a really excellent series of jazz shows curated by their new artistic director, the great Detroit-raised pianist Geri Allen, with significant involvement from bassist Rodney Whitaker's MSU jazz program.
