Miller Theatre is not kidding around this week, with a Brian Sacawa saxophone recital on Wednesday (works by Alvin Lucier, Martin Bresnick, Michael Gordon, u.a.), a Music from Copland House concert on Thursday (the Copland sextet, Sebastian Currier premiere), and a putatively delirious Alarm Will Sound show on Saturday (Nancarrow, Ligeti). Also on Wednesday, Church of St. Ignatius Loyola rolls out Schnittke's grand, mysterious Concerto for Choir, alongside other sacred Russian works. And two performances remain of Gotham Chamber Opera's Ariadne in Crete, on Tuesday and Friday.
