What would Schubert have done if he had heard Domenico Dragonetti play? It’s perhaps not one of the world’s great musical mysteries – Dragonetti was a great virtuoso double bassist, Schubert was fond of the instrument – but this recording provides the answer: a fun new version of the C Major String Quintet, arranged for string quartet plus double bass instead of the usual extra cello. We forfeit the sweetness of the two cellos crooning their high tenor duets, but instead we get heft, and an added darkness that matches the angst beneath the work’s tuneful surface. The Finale theme gains the oomph of a bawdy tavern song and there’s a resounding kick to the Scherzo. The only place the arrangement doesn’t work is in the rapturous Adagio, where chunky pizzicato interjections keep things earthbound. The playing is terrific: tasteful phrasing, gracious ensemble intuition and a string sound that’s fibrous, luminous and poised.
