Cold, and snowy!, winter nights have us ready for hot jazz, and the Cape has some wonderful live venues. The Carol Wyeth Duo can be found Saturday evenings at the Oyster Company on Depot Street in Dennisport. Christa Dulude can be found singing jazz classics Sunday evenings from 5-8PM at Jake Rooney's on Brooks Road in Harwich Port. The Black Cat on Ocean Street in Hyannis has a piano bar on Sunday through Tuesday evenings.
