Howard Griffiths’s ‘Next Generation Mozart Soloists’ series has done sterling work in promoting young musicians and giving them valuable studio experience at the highest level. For the Sinfonia concertante – perhaps the greatest of Mozart’s Salzburg concertos – Griffiths has selected two players who are already at the forefront of their respective fields: the Swedish violinist Johan Dalene and the Norwegian viola player Eivind Ringstad. Both are veterans of the recording studio and both are serial award-winners, 23-year-old Dalene Gramophone’s 2022 Young Artist of the Year, Ringstad (just turned 30) a former Eurovision Young Musician, both of them past members of BBC Radio 3’s New Generation Artists scheme.

This pedigree is indicative of the star quality they bring to the Concertante, Dalene’s tone radiant without being self-consciously sweet, Ringstad’s rich and woody, each playing off the other in this exquisite dialogue. Their meeting of minds and matching of techniques brings the surest of dividends in the cadenzas of the opening movement and central Andante, while they strike sparks off each other in the carefree interplay of the contredanse finale.

These high standards are maintained as the programme continues. Alexandre Zanetta is unerringly accurate and uncommonly expressive on a valveless instrument in the Horn Concerto No 2, making a virtue (as did Mozart) of the horn’s natural inconsistencies and enjoying to the full the effects it offers. And Ariel Lanyi is poise personified in two Rondos written as replacement movements for Mozart’s piano concertos – neither of them among the composer’s most penetrating creations but both pleasing in their own right. It’s an odd coupling but all the performances are accomplished and attractive, and often far more than that. Griffiths and the Salzburg Mozarteum players accompany with authority and a clear sense of period style on modern instruments.
