The collection of toccatas Apparatus musico-organisticus, published in 1690, immediately established Georg Muffat as one of the greatest organists of his century. A veritable reference in the organ repertoire, appreciated for its stylistic diversity, this work testifies to Muffat's ambition to blend European styles while exploring the expressive possibilities of the Baroque organ. Bernard Foccroulle deploys a range of emotions that underline the breadth and harmonic richness of the toccatas, performed on an organ emblematic of the French style that suits them so well, to which is added the delicate Sonata a violino solo, executed with brio by Marie Rouquié.
