Canadian art-punk group, The Constantines will treat somewhere on the order of 300 Bostonians to their unique amalgam of Fugazi and Springsteen this Friday at TT the Bear’s Place. They’ll be drumming up support for their forthcoming album, Kensington Heights, which is due on Arts and Crafts tomorrow in Canada and two weeks later in America. Kensington Heights is their fourth album since their 2001 self-titled debut and their first for Arts and Crafts.
