Lettuce, those new-school purveyors of old-school funk and soul, are celebrating their 20th anniversary this year, and what a 20 years it’s been. Having risen from playing tiny night clubs to gracing huge stages like The Fillmore in San Francisco, the band show no signs of stopping any time soon. The Brooklyn-based collective has developed a reputation as one of the best live bands going; trust us when we say that that reputation is more than earned. Our nation’s capital will get to experience that live power first hand when Lettuce stop by the legendary 9:30 Club. For more information and to purchase tickets, visit the 9:30 Club website.
