I’ve heard only good things about Chicago’s Anubis Quartet, a saxophone ensemble that’s part of the thrilling wave of new-music ensembles devoted to new work, but I regret that I haven’t had a chance to actually catch a performance by them. I’m planning to rectify that situation on Monday night when they play a fantastic-looking program at the Nichols Concert Hall in Evanston. The group includes Ryan Muncy, the executive director of Ensemble Dal Niente, which has amply demonstrated its versatility, curiosity, and virtuosity over the last few seasons, and I have no reason to expect any less from Anubis. The group also includes Allison Balcetis, Michael Ibrahim, and David Wegehaupt.
