Antonin's trusty name is being used to lure in an audience for this one-off afternoon gig at 92Y, in which star cellist Alisa Weilerstein and members of the New York Philharmonic escape from this week's Lincoln Center duties. But the program is at least as much about unfamiliar music as it is about Dvorak. The works of the other Czech composers on this bill, Martinu and Schulhoff, are worth the price of entry alone. (Schulhoff's jaunty Divertissement may be the highlight.)
