Mark Braud was born June 21, 1973, into one of the great musical families of New Orleans — on both sides. He is the grandson of trumpeter, pianist, and composer John “Picket” Brunious Sr., the nephew of trumpeters Wendell Brunious and the late John Brunious Jr., and a distant relative of Duke Ellington Orchestra bassist Wellman Braud. He picked up the trumpet at twelve — his uncle Wendell gave him his first cornet — studied at NOCCA and majored in jazz studies at the University of New Orleans under Ellis Marsalis, and came up through the city’s brass bands, starting with the Olympia Kids.
In 2001 he joined Harry Connick Jr.’s big band, eventually becoming Connick’s featured trumpet soloist, touring and recording with the band and appearing in Connick’s Broadway shows and his syndicated TV show, Harry. From 2008 to 2016 he led the Preservation Hall Jazz Band, taking over the New Orleans unit from his uncle Wendell. Along the way he has played with everyone from the Marsalis family and the Treme Brass Band to the Foo Fighters, Tom Waits, My Morning Jacket, and Erykah Badu; his screen credits include A Tuba to Cuba, NCIS: New Orleans, Treme, and Broadway’s One Mo’ Time. In 2023 he co-founded the production music library Old Saw Music, and in 2025 he founded the traditional Colossus Brass Band.
