Espers is a psychedelic folk band from Philadelphia, PA, United States. They formed in 2002 as a trio of singer-songwriter Greg Weeks, Meg Baird and Brooke Sietinsons but later expanded to a sextet including Otto Hauser, Helena Espvall and Chris Smith. Their music is reminiscent of late-sixties british folk such as that of Fairport Convention, Pentangle and The Incredible String Band as well as many contemporary folk acts such as Six Organs of Admittance, Marissa Nadler and Nick Castro and as such their work is often lumped in with the so-called new weird america movement or naturalismo as Devendra Banhart preferred to coin it in 2006.
