Since launching the fledgling Broadway @ The Art House concert series with Sirius XM Radio Star Seth Rudetsky in Provincetown in 2011, the Broadway @ series has become a veritable star-magnet and has exploded beyond picturesque P-Town to launch outposts everywhere from Los Angeles to London. Broadway @ The Performing Arts Center is sponsored by Cape Air, Harbor View Hotel and Hy-Line Cruises. The Broadway @ the Performing Arts Center concert series will help raise funds for the Tyler Clementi Foundation. For tickets to all performances please visit www.vineyardbroadway.com.
