Brinnel's music is rooted firmly in the original intentions of 1920s-1940s jazz, arranged such that the energy is preserved but new life is undoubtedly breathed into them. Acclaimed trumpeter Terell Stafford praises Brinnel for “honoring the history of this music” and sounding “so pure and soulful” that “I can’t stop listening!”
