Marc Boon has been the lead vocalist, rhythm guitarist, keyboard player, and band leader since Hip Pocket began. His versatile vocal style makes the transitions between Hip Pocket's varied repertoire of swing, blues, R&B, and classic rock smooth and seamless.

Jim Boitos, Professor Emeritus of Music, taught saxophone and jazz at Illinois State University for thirty six years. Throughout his career as a professional musician, Boitos has performed with such notables at Billy Eckstine, Big Joe Williams, Cab Calloway, Nancy Wilson, the Temptations, Mary Wilson, Anne Hampton Callaway, and many more. He has joined Hip Pocket in order to keep a watchful eye upon several of his past (way, way past) students.

Bassist Chris Briggs' talent for laying down the sturdiest of foundations has been a hallmark for Hip Pocket for nearly 19 years while he also has lent his talents as an accomplished pianist and arranger on several songs from HP's 5 CDs.

Gary Erwin has been known throughout the local music scene as a rock solid drummer for 30 plus years and is the perfect playing partner when it comes to the diverse styles of music Hip Pocket performs.

Jeff Estes brings the perfect blend of superior musicianship and ultimate team spirit to Hip Pocket and is just at home on baritone sax as he is on alto, tuba, (Marc can't wait to find the perfect tune for that one), clarinet, or singing the highest of harmonies.

Tom Fatten is an accomplished arranger, musician, and performer who can play it all from big band charts to the classics. He’s at home playing piano, bass, trumpet or singing a few higher harmonies and brings a sense of order to this disorderly bunch. Another of those serious musicians who actually studied and got a degree.

Trombone, trumpet, percussion, and vocal harmonies are all part of John Filkins' vast talents. John has anchored the "I'm just glad to be here" horns for 22 years and has helped arrange many of the horn charts.

John Kerner adds soulful guitar riffs and blazing pyrotechnics with tasteful ease as Hip Pocket's lead guitar player and lends a few high and lonesome harmonies along the way.

Tom "Roomer" Wiedrich's unique character is hard to ignore whether he's belting out a vocal, lippin' the harp, or supplying the rolling boogie woogie piano and riveting B-3 sounds that fans have come to love.
