One can never have enough Mozart or Brahms Clarinet Quintet recordings in a collection. With both composers in mind, I wish Jörg Widmann would have added the Brahms to the Mozart rather than the accompanying Mozart String Quartet K421. His playing is that good. A revelation, actually.
Not that you’ll be slumming with the superb Arcanto Quartet (founded in 2002). They perform Mozart as well as any and you’ll love their performance of the second of the so called ‘Haydn Quartets’ (No. 15 in D minor K.421). Dedicated to ‘To my dear friend Haydn’, the performance by the Arcantos will have you wishing for a complete set.
