Busker is British for street musician. The Cambridge Buskers—so named because the duo met at Cambridge University—have good credentials. They've been busted for busking in Paris and in a bucolic English village, ordered to move on in a London Underground station and in Hamburg, among other spots. In Cologne, they fared better, meeting the composer Karlheinz Stockhausen, who tossed them two marks, praised their cheery flute-and-accordion arrangements and subsequently sent them a composition dedicated to them. Nowadays, Michael Copley, 26, the flutist, and Dag Ingram, 27, the accordionist, perform their clever, short arrangements of the classics from Japan to Miami and in the recording studios of Deutsche Grammophon, the august classical label. Not Live from New York, their second album, was, true to its title, recorded in London and Hamburg, though the cover photos were shot in Brooklyn. Both men are highly accomplished players, especially Copley, who is sensuous on flute, robust on recorder. The 16 pieces—all under four minutes—range from snippets of Bach, Vivaldi, Handel and Mozart to the Sabre Dance from Khachaturian's Gayané ballet, Schubert's Marche Militaire and The Dying Swan from Tchaikovsky's Swan Lake. If it's musical candy, best consumed after a hearty meal of the real thing, at least there are no artificial ingredients.
