When Lewis Black calls a comedian “the funniest comedian in America, bar none,” you probably don’t want to miss that artist (or risk crossing Black in general). That said, the 25-year comedy veteran, Kathleen Madigan, has previously performed on Last Comic Standing, Conan O’Brien, The Late Show With David Letterman, as well as on her own specials on HBO and Comedy Central. Now, she will be continuing her Madigan Again tour at the Victoria Theater at the New Jersey Performing Arts Center on Sept. 18.
