BARBARA HANNIGAN at the Park Avenue Armory (Oct. 15 and 17, 7:30 p.m.). If we could just hear more of Hannigan, one of the great sopranos of our time, now making waves as a conductor, too. Her only scheduled New York appearances of the season feature music by John Zorn, including “Pandora” with the JACK Quartet and “Jumalattaret” with the pianist Stephen Gosling, on Tuesday; and by Schoenberg, namely his String Quartet No. 2 with the Emerson String Quartet, on Thursday.

PHILADELPHIA ORCHESTRA at Carnegie Hall (Oct. 15, 8 p.m.). Yannick Nézet-Séguin has a Perspectives series this year. It’s an honor that some artists have treated as an opportunity for experimentation; instead, he is mostly wasting it on one of this season’s two cycles of the Beethoven symphonies, which the orchestra will return to perform at Carnegie starting in March. No Beethoven in this opening concert, though, rather Strauss’s “Eine Alpensinfonie,” Valerie Coleman’s “Umoja” and Bartok’s Piano Concerto No. 3. Hélène Grimaud is at the keyboard.

DANIIL TRIFONOV AND SERGEI BABAYAN at Carnegie Hall (Oct. 16, 8 p.m.). Trifonov and his teacher have made an endearing double act in their performances together, but my colleague James R. Oestreich wrote in a review of their Carnegie recital last year that they also have a “firepower” that is “rare among piano duos.” Here they play Schumann, Ravel, Rachmaninoff and Prokofiev, in a transcription of “Romeo and Juliet” by Babayan himself. Pianophiles should note, too, that the next night at Carnegie (Thursday at 8 p.m.) the wonderful Beatrice Rana performs two of Bach’s keyboard concertos with the Orchestra of St. Luke’s.
