Hesterian Musicism is not only the name he coined for his performance ensemble, but it also designates Hester's compositional and improvisational process. Hesterian Musicism is the creative process through which Karlton Hester's compositional and performance style merge to give rise to aesthetic environments where other musicians, kinetic and visual artists, and poets can meet to produce new art forms through imaginative effort. Its philosophical basis involves an intrinsic freedom of expression, focused and disciplined spontaneity, and a structural basis that explores the creative components of diverse sources from the whole earth. Intrinsically interdisciplinary, Hesterian Musicism has presented numerous concerts in collaboration with other artists, such as painters, dancers and choreographers, poets, as well as a number of performances featuring African musicians on traditional instruments.
