Many of this blog's readers were scandalized when I advised against giving money to such major local players as the BSO and MFA. How better could their money be spent?, some wondered. Well, here's one way: by bringing Mozart Dances, by Mark Morris, to Boston. We're just about the only one of his traditional touring spots that isn't seeing it this year. We will be seeing him, yes, in the recast Dido and Aeneas - but why can't we see both?
