Louis played in the Cherry Blossom Band and then led his own group, the Magnolia Band, which included King Oliver and Honore Dutrey among its members.
He played with Papa Celestin's Tuxedo Brass Band and Manuel Perez, and following this with the Olympia Orchestra alongside Freddie.
His style of "shuffle rhythms" was an influence on Danny Barker.
