French composer Clément Philibert Léo Delibes (1836-1891) is best known for his stage works, including the opera Lakmé and the ballets Coppélia and Sylvia.  He studied composition at the Paris Conservatoire under Adolphe Adam, also taking lessons in voice and organ while there.  These secondary studies landed him his earliest jobs as a chorus master and accompanist, first at the Théâtre Lyrique and later at the Paris Opéra.  He eventually returned to the Conservatoire in 1881 as a composition professor.

The March and Procession of Bacchus comes from his 1876 ballet Sylvia, which tells the story (based on the 1573 play Aminta by Torquato Tasso) of the titular nymph and her escapades with hunting and love set amidst Greek mythology.  Sir Frederick Ashton, who choreographed a 1952 production of the ballet, summarized the plot as “Boy loves girl, girl captured by bad man, girl restored to boy by god.”  The March comes at the beginning of the final act as our hero (Aminta) seeks the love of our heroine (Sylvia) at a bacchanale.  Read more about it here and here.  Here it is in its original orchestral form:

At least two different band versions exist.  Here is an arrangement by Joseph Kreines:
