Aerosmith have let it slip where they’ll play their surprise concert at noon in Boston today. It will be in front of 1325 Commonwealth Avenue, where the band lived from 1970 to 1972. Players from the New England Patriots and some of the cheerleaders will be there too. The concert is to mark the release of the new Aerosmith album, “Music From Another Dimension,” out tomorrow. It’s also a nonpartisan get-out-the-vote party.
