Remixing a Pulitzer Prize-Winning Work New Amsterdam Presents, the feisty alt-classical label and concert-presenting organization that the composers William Brittelle, Judd Greenstein, and Sarah Kirkland Snider started in 2007, is collaborating with the Q2 Music web page on an unusual fund-raising project for the company. Every Wednesday for eight weeks, starting Nov. 13, Q2 will stream a remix of Caroline Shaw's "Partita," for which she won the Pulitzer Prize this year. The streaming tracks are freely available, but if you want to download one, or all eight, the page provides a link to New Amsterdam's fund-raising page, where you can make a donation (the amount is not specified, but it is tax deductible) and download the tracks. Ms. Shaw's original work was an a cappella work for the vocal octet Roomful of Teeth, but the remixers are free to take the music where they like. The first is an atmospheric electronic piece by Lorna Dune Krier, a member of the ensemble Victoire (which records for New Amsterdam, as does Roomful of Teeth) and a pianist and composer in her own right.
