The winner of David Lang's YouTube-driven piano competition is Peter Poston, of Melbourne, Australia. Congrats! The runners-up are Catarina Domenici, of Porto Alegre, Brazil; Katherine Dowling, of Saskatchewan, Canada; and Denise Fillion, of Queens, NY. All four will perform at a Poisson Rouge concert on May 6, and one can only hope that Mr. Poston makes no changes to his hair.
