Just one tonight, guys, and it’s part of the Earshot Jazz Festival:Eldar Trio at Tulas, 8:30 p.m., tonight and tomorrow, $10-$18I’m not sure anyone at Earshot has the kind of major-label backing that supports this 22-year-old Kyrgyz-American phenom, signed to Sony five years ago. The public loves prodigies, but Eldar Djangirov is way beyond that. If you have even a passing interest in piano, you have to check out his astounding technical facility–which fortunately is put in the service of some impressive music-making. Like the Bad Plus, the trio falls outside any of jazz’s usual boundaries. MARK D. FEFER
