Mosaïques et Beethoven.

This film portrays the Quatuor Mosaïques from the first rehearsal of Beethoven's Quartet No. 14 opus 131 until the day of its premiere. Santiago's camera spies on the rehearsals and witnesses the meticulous analysis of the musicians deciphering the score. It is not a scholarly or virtuous film; is a passionate document about the perfectionism of technique
