I forgot to give you your usual Weekend Concert Calendar yesterday...but it's OK! Because according to my regular sources, there was no choral music to be had in Boston.
However, there is a Masterworks Chorale summer sing this Tuesday! John W. Ehrlich will conduct Vivaldi’s Gloria "with accomplished soloists and expert piano accompaniment." This is Tuesday at 8:00 pm at the National Heritage Museum, Marrett Road and Massachusetts Ave, Lexington, MA. It's always advisable to bring your own score to any sing in case they run out, but their website says you can borrow one for free! As they say, this is a great way to keep in vocal shape over the summer.
