Might look un- prepossessing, but this is the view an hour before the premiere of the fantastic production of Puccini's "La Bohème" by LoftOpera, the inspired project of one of our alums. We're in a converted warehouse in a desolate part of East Williams- burg. The musicians and singers are young, many still at the Mannes School of Music, and fabulously gifted. To really feel the world of the Rodolfos, Marcellos and Mimis of today, go see it yourself - there are two more performances, next weekend. Best $20 you'll ever spend.
