Hindemith liked fun, and this ensemble -- named after the composer's own -- is eager to show they get all the jokes. The opening and finale movements of the String Quartet No. 2 (the first piece here) have all the experimental jauntiness that Hindemith was cheerfully grafting on to the tonal tradition. The other piece -- the composer's third string quartet -- is a more serious item (especially in the middle movement), but the players deck it out with delight where appropriate. This first volume of a complete Hindemith string quartet cycle is a welcome announcement.
