パリ音楽院管弦楽団
Garcin's association with the Orchestre de la Société des Concerts du Conservatoire began in 1860, again as orchestral and then as solo violinist. In 1885, he was elected principal conductor of the Conservatoire concerts. In this post he actively promoted German choral and symphonic masterpieces, from Bach's Mass in B minor (in 1891) to works of Brahms and Wagner (Brahms's music was then the object of much adverse criticism in Paris during the Franco-Prussian War). He was a founder-member of the Société Nationale de Musique in 1871. He wrote some music (including a violin concerto and viola concertino), a certain amount of which was published by Lemoine.
