Remixers start your … laptops. Some hot-off-the-presses news about a contest beginning at noon TODAY!   Pulitzer Prize–winning composer Steve Reich, Nonesuch Records, and Indaba Music have launched a search for collaborators to remix the third movement from Reich’s 2×5. Paired with his Pulitzer prizewinning Double Sextet, the work appears on Reich’s new Nonesuch CD.   For four weeks beginning October 12, 2010 at noon, remixers can visit Indaba’s website to create their own version of the movement. From November 9 to 23, fans and a panel of judges including Reich will review the submissions. Winners will be announced on December
