Al Chesis supplies vocals & foot stomping showmanship but it's his harmonica playing that grabs you. He has been a Hohner endorser since 1992. Al recently received a Colorado Blues Society Lifetime Achievement Award. Bob Pellegrino supplies the dazzling, slide guitar. Bob was the Colorado Blues Society's best slide guitar player in three years in a row. Rising bass star Alissa Chesis and Stefan Flores on drums drive the bus, and are a grooving rhythm section.
