The 9:30 PM concert – under the musical direction of Dan Lipton (Don't Quit Your Night Job) – was inspired by a previous performance by Plimpton and Roche at Joe's Pub, which was later included on Roche's EP "8 More." For the Zipper concert, Plimpton and Roche will perform a selection of Roche's music as well as their favorite songs. Joining the duo will be August: Osage County's Jim True-Frost and Sally Murphy, Loudon Wainwright III, Suzzy Roche, John Wesley Harding, Julian Fleisher, Dave Hill and Bridgett Everett (At Least It's Pink). The evening also promises last-minute surprise guests.

Plimpton earned Tony Award nominations for her work in The Coast of Utopia and Top Girls. Her New York stage credits also include Cymbeline, A Midsummer Night's Dream, Shining City and HurlyBurly. Plimpton will make her Broadway musical debut as Gladys Bumps in the 2008 Roundabout revival of Pal Joey.
