This CD, with its companion CDA67254 (available separately), presents all of Beethoven's music for string trio, even including the alternative 'trio' (Hess 28) of the Scherzo movement of Op 9 No 1. Although these works bear early opus numbers they should not be regarded as anything other than first-class, mature Beethoven. They are fine, absorbing pieces, not as well known as they should be—a state of affairs which these wonderful CDs should do much to rectify.
