Theon Cross is a composer and tuba player who has been redefining the role of the instrument in modern jazz through his work with Moses Boyd's Exodus and Sons of Kemet. His solo work stylistically remains in line with the kind of jazz popular among London-based musicians: funky, rhythmically sophisticated, drawing on Caribbean and African influences, as well as some of the more recent genres, such as grime. Cross is not only a solid rhythmic contributor but he also has a strong melodic side that comes through very clearly. His 2021 work, Intra-I, finds him exploring electronic music, setting his riffs against programmed beats that are often paired with the delivery of a guest rapper.
