Les Dissonances is a collective of artists founded by violinist David Grimal in 2004. The conductorless ensemble consists of musicians from the most prestigious European orchestras, international soloists, and young talents. In this performance, Les Dissonances' string quartet - consisting of David Grimal (violin), Hans Peter Hofmann (violin), David Gaillard (viola), and Xavier Phillips (cello) - performs Wolfgang Amadeus Mozart's String Quartet No. 19 in C major, K. 465, 'Dissonance' (Op. 10 No. 6). The String Quartet is the last in the set of six quartets that were dedicated to Joseph Haydn. Written between 1782 and 1785, these are also known as the Haydn Quartets (Op. 10). String Quartet No. 19 is remarkable for its slow, dissonant introduction, giving the piece its nickname. This ominous passage suddenly gives way to the bright Allegro in C major. This performance was recorded at Opéra Comique in Paris, France, in 2015.
