Oeuvre: Tusen Tankar (A Thousand thoughts)

Roulette has never looked so snazzy: the usual dishevelled hipsters were replaced by well-dressed audience members of all ages, wearing heels rather than flannel, drinking from wine glasses rather than beer bottles.

The program page for Kronos Quartet’s program at the Cleveland Museum of Art on 18 January was typical of their concerts: a daunting list of mostly unfamiliar composers and every work either written or arranged for Kronos (David Harrington and John Sherba, violins; Hank Dutt, viola; and Jeffrey Zeigler, cello).

It's remarkable that the 39-year-old Kronos Quartet had never played at the Proms before this Tuesday evening, but they seemed set for making up on lost time, with a literally spectacular performance of a typically diverse range of works from around the world.
