Big Bad Voodoo Daddy will bring its upbeat style of jazz to Discovery Park Saturday, June 21, as part of the L.L. Bean Summer Concert Series in Freeport. The band’s jumping swing style and musical repertoire is true to tradition with ’40s-style horn arrangements. Yet, the band has created a style uniquely its own. The free outdoor concert will begin at 7:30 p.m. Bring a lawn chair.
