Music of Chris DeBlasio, Kevin Oldham, and others at the annual Benson AIDS Concert for World AIDS Day.... Does Andris Nelsons have a Boston future? Now that Riccardo Chailly has withdrawn from his much-talked-about Boston Symphony dates next month, attention turns to the gifted young Latvian, who is scheduled to lead a program in early January. It's interesting that he's been given a role in the Tanglewood 75th-anniversary gala.... Good news from Other Minds: early next year they're reissuing Michael Tilson Thomas's survey of the works of Carl Ruggles, a classic two-LP set that never appeared on CD.... This weekend, the Postclassical ensemble, of Washington, DC, presents a full production of Falla's El amor brujo, with dancers from the Peridance company. Tickets are $25 — about the same as Jay-Z's Occupy Wall Street T-shirt.... Next week, the mighty JACK Quartet plays a program of Earle Brown, Peter Ablinger, Horaţiu Rădulescu, and Alex Mincek (his striking Third Quartet) at the spectacular EMPAC venue in Troy, New York. Tickets are $18 — a bit less than Jay-Z's Occupy Wall Street T-shirt.... Augustin Hadelich, one of the most characterful of younger violinists, plays in the Peoples' Symphony series this weekend. Tickets are $13 — significantly less than Jay-Z's Occupy Wall Street T-shirt, and about a fifth the price of the cheapest tickets for Jay-Z and Kanye West's show in Chicago tonight.... The excellent new group yMusic appears at Rockwood Music Hall on Sunday. Tickets are $10 — etc., etc.... Speaking of Occupy Wall Street, Philip Glass will address a protest at Lincoln Center tonight, following the final performance of Satyagraha. Glass's masterpiece will be seen again in the HD Live series on Dec. 7.
