Jenny Lewis has a great sense of when to deploy her friends (take the delightful "She's Not Me" music video). So it's not surprising that she successfully brought out Annie Clark, a.k.a. St. Vincent, as a special guest at the Trans-Peco festival in Marfa, Texas, where we can say with certainty that no one called them Lewis and Clark at all (definitely, definitely not). Watch some video from the performance below, starting with their cover of "Groove is in the Heart," via Pitchfork and Consequence of Sound.
