This is going up a little later than usual, but hopefully this will still be of use!
Friday: Celebrity Series Boston is bringing Sweet Honey in the Rock! Wooo! 8 pm, Symphony Hall. They are AWESOME and that is all there is to say about that.
Also on Friday: MIT Concert Choir.
Saturday: For Saturday, I recommend a town: Concord. The Concord Women's Chorus is doing one fascinating program at 2 pm at Trinity Episcopal Church in Concord. It will feature Andrew Carter's Missa Brevis, Michael Isaacson's Cradle of Fire, and Gregg Smith's Latin Madrigals. Then at 7 pm the Concord Chorus (a mixed group) will be doing an excellent program featuring Barber's Reincarnations and selections from Argento's Walden Pond at 8 pm at the New Church in Concord. (And in between Concord features plenty of places for pretty walks and delicious dinners!)
Also on Saturday: A Cappella Singers, Assabet Valley Mastersingers, Capriccio Children's Chorus, Harvard Pro Musica, Jubilate Chorale, Master Singers of Lexington, Newton Choral Society, Simmons College Concert Choir.
Sunday: How appropriate that on Mother's Day the MIT Concert Choir should be singing Haydn's Creation! 4 pm, Kresge Auditorium on the MIT campus in Cambridge.
Also on Sunday: The deVaronistas.
Did I miss anything? Leave it in the comments!
