About Bonegasm

In the jazz world, trombone tends to be treated as an afterthought. If a small group has a trombone in it, it’s likely because the bandleader is the trombonist. Bass trombonist Jennifer Wharton wondered what might happen if composers and audiences alike encountered music that featured the beauty of the instrument. 

She created Jennifer Wharton’s Bonegasm in 2017, a seven piece jazz ensemble featuring four trombone and rhythm section. Wharton is a prominent low brass player in NYC on Broadway and in the big band and recording world and once was considered a unicorn in the world of music. In the not-too-distant past, it was a rarity to even have a woman in prominent jazz bands and orchestras, but to have a bass trombone-slinging woman as leader was thought extraordinary. With Bonegasm, she elevates both women instrumentalists and the trombone family itself.

Bonegasm performs arrangements and originals commissioned from prominent composers as well as members of the ensemble. Bonegasm has commissioned over 3 dozen works in 8 years from jazz stalwarts like Jim McNeely and Rufus Reid as well as newer faces like Vanessa Perica and Darcy James Argue. 

Bonegasm’s debut album, Bonegasm (Sunnyside, 2019) made the Billboard Jazz Chart its first week. It was followed by Not A Novelty (Sunnyside 2021) which was deemed “Trombone Ecstasy” by Downbeat Magazine. The latest album, Grit & Grace, was released on Sunnyside Records in October 2023. JAZZIZ said the music “captivates as it ranges between the intimate and the orchestral with plenty of whimsy.”

The response to Bonegasm’s music was astounding, cementing Wharton’s assertion that this assemblage was no flash in the pan but an important exponent of shaping the trombone’s primacy in jazz music. 

Bonegasm has received grants from New York Foundation of the Arts, Chamber Music America and Jazz Road.

Jennifer Wharton might be considered by many as a unicorn in the world of music. In decades from the not-too-distant past, it was a rarity to even have a woman in prominent jazz bands and orchestras, but to have a bass trombone-slinging woman as leader was thought extraordinary. In 2019, Wharton presented her trombone-powered ensemble, Bonegasm, via its self-titled debut album.

Wharton enlisted fellow trombonists John Fedchock, Nate Mayland, and Alan Ferber, along with the rhythm section of pianist Michael Eckroth, bassist EvanG regor, and drummer Don Peretz. The music performed included originals and arrangements the leader commissioned from prominent composers she knew as well as members of the ensemble.

The overwhelming response to Bonegasm’s music was astounding, cementing Wharton’s assertion that this assemblage was no flash in the pan but an important exponent of shaping the trombone’s primacy in jazz music. Bonegasm’s new recording, Not a Novelty, wears its intentions on its sleeve, or perhaps more appropriately, tattooed on its arm.

4 1/2 stars – “From afar, this album may seem like nothing more than a novelty project, but the music successfully argues against that thinking. Jennifer Wharton’s Bonegasm blows the doors wide open for the bass trombone. The horn itself may play from the bottom, but it can certainly operate at the top of the heap.”
