Mark Monistere - Vocalist, Saxophonist

With a father who was a bandleader, brother and sister playing classical piano, and his uncle a drummer, Mark grew up in the New Orleans tradition of a musical family. His musical career started at the early age of four years old when he received a curved soprano saxophone. Mark said at this time his major musical influences were a mixture of 1950s doo-wop and rock and roll groups, and New Orleans Traditional Jazz Bands. Performing on stage with his father’s band provided an experience that help shape him as a musician and an entertainer. Mark performed at Mardi Gras balls, on national television shows, for NFL Player parties, and for John Paul D’ Joreo, owner of Paul Mitchell hair products. At this time he was developing his piano and singing abilities in front of crowds that were surprised to hear such an old style come out of such a young man. Mark was taking classical piano lessons from his teacher, and at the same time he was learning jazz and doo-wop at home. His musical influences started to include singers such as Frank Sinatra, Tony Bennett, Louis Prima, Stevie Wonder and Otis Redding. Mark became the first High School Louisiana All-State Jazz Vocalist. While learning and performing the music of great singers, Mark became heavily influenced by the music of tenor saxophonist John Coltrane. Performing mainly as a singer, his musical focus at home shifted to the saxophone. He then went on to get a undergraduate and masters degree in Jazz Saxophone from the University of New Orleans, performing in Big Bands directed by Ellis Marsalis, and studying with the great tenor saxophonist Ed Peterson.

In his professional career, Mark continues to perform in a wide variety of musical styles. Learning bebop and the music of many great jazz saxophonists was the major focus in his practice. He performs songs that had been popularized by singers such as Frank Sinatra, Dean Martin, Nat King Cole, Louis Prima, and Louis Armstrong. Listening extensively to Bach, Bobby Mcferrin, Johnny Hartman, and Kurt Elling, Mark became inspired to revisit the melodies of singers who’s music he had grown up with. At this point, fully embracing his role as a singer, he began to wow crowds with his ability to showcase his passion for the music with the cool confidence of a much older entertainer. Mark has shared the stage with Allen Toussaint, Ronnie Kole, Clarence “Frog Man” Henry, Edward Peterson, Leah Chase, Ellis Marsalis and many others. His voice is reminiscent of the styles of Sinatra, Harry Connick Jr, and Michael Buble with a unique presence of his own sound. Mark performs with the intensity of a jazz saxophonist combined with the playfulness, confidence, and smoothness of a great singer and entertainer.

Brad Walker - Saxophonist


Brad Walker was born in Asheville, North Carolina, a city with a vibrant, creative culture that left a lasting impression. He began playing clarinet at age 11, switching to saxophone after one year. At Louisiana State University, where he enrolled in 2002 with a full music scholarship, Brad studied with saxophonist Dr. Griffin Campbell, a virtuoso classical performer who provided impeccable instruction as to technique and tone production. In addition, Brad studied improvisation and jazz with Dr. Willis Delony, Dr. William Grimes, and Prof. Brian McWhorter. As a soloist, Brad was featured as a classical performer with the Rapides Symphony, as their 2006 Concerto Competition winner, and also on numerous occasions as soloist with the LSU Jazz Ensemble, in which he played lead tenor for his entire college career.

Upon graduation, Brad spent two years in New York City. In addition to occasional gigs with Simon Lott and other musicians in the city, Brad twice participated in the School for Improvisational Music's NYC workshops, and was afforded the chance to see such luminaries as Joe Lovano, Paul Motian, Keith Jarrett, and Terence Blanchard on many occasions, all of whom had a major influence.

 In 2009, Brad decided to return to Louisiana and dedicated himself full-time to music. In addition to successful pursuit of a Master of Music (Jazz Studies - 2011) degree from LSU, his career as a saxophonist in New Orleans and the region has quickly taken off. In addition to frequent performances with local New Orleans luminaries Simon Lott, Helen Gillet, Jonathan Freilich, Aurora Nealand, Jeff Albert, and others, Brad regularly tours the Gulf Coast region—from Key West, FL, to Houston, TX (and everywhere in between)—with guitarists/vocalists Thomas Johnson and Cam Pyle.
