There's an awkward pile-up of events on Saturday, all of which I'd ordinarily like to see. Soheil Nasseri, the gifted young pianist whom I mentioned at the end of my Lupu column, is giving another recital at Alice Tully Hall. The program includes the premiere of a piece by the Israeli composer Avner Dorman. Tickets are $10 for those under 25. Simultaneously at Merkin, the Azure Ensemble is playing new and new-ish works by Libby Larsen, Judith Shatin, Jennifer Higdon, Marilyn Bliss, David Stock, and Zhou Long. I've never heard the group but the performers are all solid new-music veterans, and there's something poetic simply about the titles: Black Birds, Red Hills; Three Summers Heat; Light Refracted; Under the Azure Sky; A Vanished World; and The Elements. Finally, at 10PM downtown, Vox Novus will be presenting the video version of its 60 X 60 project — a series of 60-second works by 60 composers.
