Lucien Garban studied at the Conservatoire, and subsequently made transcriptions of works by Debussy and Ravel; he was among the audience at the first performance of Pelléas et Mélisande. He went on to become a proof-reader of scores at Durand, the music publishers, and he was a lifelong friend of Ravel. He received frequent letters from him requesting arrangements to be made about his scores and contracts. Garban sometimes used the pseudonym Roger Branga for his own compositions and transcriptions.
His adaptations of works by Ravel (usually transcriptions for piano solo or duet) included versions of the string quartet, the Introduction & allegro, the Rapsodie espagnole, the Valses nobles et sentimentales, Ma mère l'Oye, the piano trio, the Kaddisch, Le tombeau de Couperin, the Berceuse, and Boléro. Garban was also active in dissuading Ravel from attempting to give the first performance of his Piano concerto in G (Long,  p.60).
