Bernstein founded his first record label, Vendôme, in 1954, which released only 5 LPs.
The first release was the world premiere recording of Debussy's Proses Lyriques, by Flore Wend a Swiss soprano living in Paris, accompanied by the pianist Odette Gartenlaub, engineered by André Charlin, and recorded at the Salle Adyar, Paris.
