Mozart adored writing for woodwind instruments—his Clarinet Concerto, completed towards the end of his life, is one of the instrument’s finest works. But a decade or so before, the composer conceived the “Gran Partita”, an extraordinary, richly scored multi-movement work for 13 woodwinds, from oboe to bassoon, with one of classical music’s most heart-melting slow movements at its centre. This performance by members of the Royal Concertgebouw Orchestra is thrillingly performed and recorded in sumptuous sound.
