Let's just dive right in, shall we?
Friday: On Friday, I recommend going to see Masterworks Chorale present Handel's oratorio Alexander's Feast. The soloists will be excellent - soprano Teresa Wakim, tenor Jason McStoots, and baritone Sumner Thompson - and the Treble Chorus of New England will also be featured. At 8 pm at Sanders Theatre.
Also on Friday: BSO w/ the Tanglewood Festival Chorus, Cantata Singers, University Chorale of Boston College.
Saturday: Go to the BSO! In addition to Brahms' Symphony No. 2, they will be performing the rarely-heard Atlàntida (“Atlantis”) by Manuel de Falla. Sung in Catalan, this work is about the lost continent of Atlantis and its subsequent rediscovery by Columbus. This concert will be Friday, Saturday and Tuesday at Symphony Hall at 8 pm.
Also on Saturday: The Master Singers of Lexington, BSO w/ the Tanglewood Festival Chorus, Cantata Singers, Blue Heron Renaissance Choir, Night Song Schola.
Sunday: It's a weekend for big choral works! On Sunday I recommend the Chorus pro Musica concert, featuring Dvorak's Mass in D as well as works by Janáček, Duruflé, and Holst. 3 pm at Old South Church in Boston.
Also on Sunday: Candlelight Chorale, Divi Zheni.
