Hans Otte and Monique Hass make sympathetic soloists in The Four Temperaments and the Concert Music Op. 49, though the brass playing in the Concerto for Orchestra and Die Harmonie der Welt has been trumped many times over. All things considered, it's something of a miracle that DG made these important recordings available again. The mono sound is clear and cohesive, lacking in bass focus but otherwise perfectly acceptable and certainly listenable. The climaxes of Die Harmonie der Welt sound a bit congested, but then that's a common fault on more modern recordings too. Hindemith's star seems to be on the wane at present, but he was a major composer and hearing this set only reinforces the increasingly positive impression that his music makes as time goes on. Grab it while you can.
