In a century that saw many illustrious French and German composers write for two flutes, the six sonatas of Wilhelm Friedemann Bach stand out as the most significant, complex and technically demanding of this repertoire. Ever since they were rediscovered and published almost a century ago, they have become a stable part of the flute catalogue, appreciated and performed on both historic and modern instruments. Viewing it as the quintessential work of Friedemann's creative output, the specialist Peter Wollny even sees it as a summa of his entire production, full of quotations and reminiscences of his previous works. After the album devoted to the sonatas of C.P.E. Bach (A 537, Diapason d'or), Manuel Granatiero, accompanied by the Italo-Croatian flautist Eleonora Biscevic, now turns his attention to this masterpiece by Johann Sebastian Bach's eldest son. Arriving some thirty-five years after the first, and only, recorded version on period instruments (by Barthold Kuijken and Marc Hantai), this new recording offers a fresh perspective on music of extraordinary brilliance, passion and virtuosity.
