Hot Zone Band

A combination of diverse influences make the Hot Zone band special and exciting. We rarely play stock covers of popular tunes. Instead, we like to modify the song's arrangement and rhythmic feel to make it funkier and more danceable. With hot guitar solos, smoking blues harp, and an array of fiery keyboards we try to make the song our own.
