This is American Routes Live from Esplanade Studios with Jason Marsalis and his quintet. Jason is the sixth son of Dolores and Ellis Marsalis Jr. Three of his siblings are jazz musicians: trumpeter Wynton, saxophonist Branford, and trombonist Delfeayo. Jason is the timekeeper who played with his father and notable others: Joe Henderson, Lionel Hampton and Marcus Roberts. Pianist, composer, teacher and father, Ellis Marsalis Jr. passed on April 1st, 2020. I asked Jason Marsalis about his father, known as a modernist, about his relationship to New Orleans traditional jazz.
