WHY YOU SHOULD KNOW THEM

More than the man with the bass

01

THE BAND

He helped build B.I.G.

The group’s roots go back to 2002. Shaw’s founding role makes him part of its identity as well as its rhythm section.

02

THE RECORD

His own musical point of view

Choice, his 2017 debut album, brings the bass forward alongside a circle of featured vocalists. The bandleader also has a story to tell under his own name.

03

THE PERSON

Music alongside a demanding career

His published biography describes more than two decades in radiation protection at nuclear power stations—a striking parallel to a life spent making music.

THE STORY

Built around the pocket

A great groove creates a place for everyone: the singer, the drummer, the next instrumental reply—and the people on the dance floor. Marcus “Slim” Shaw’s story begins in that shared space. In a 2016 interview after B.I.G.’s Jazz Fest West appearance, Shaw recalled a group that began with nine players and settled into a five-piece band. The name carried a little of that original scale, but his description of the goal was personal: excellent music and a family feeling among the musicians. Fellow guitarist Robert “Bullet” Harris described hearing a bass idea from Marcus and answering it. That exchange says more about a living band than a list of genres ever could. Shaw also wanted to put his own musical choices on record. While preparing Choice, he described a meeting of funk, smooth jazz and R&B, with a bass-led title track. The album arrived in 2017. Its guest voices sit beside track names that make the instrument’s place unmistakable: Why Bass and Bass in the Face. At Campus JAX, that story becomes something you can see: Shaw at the microphone, bass in hand, playing to a room rather than an abstraction. His August 14, 2026 performance is the source of JAX Momento 003-A. It preserves a brief piece of the music—and gives you a reason to come back for the whole evening.
