Espers is a neo-psychedelic folk band from Philadelphia. 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...
They released their self-titled debut, Espers, in 2004 to much acclaim and followed that with an album of cover songs, The Weed Tree, in 2005. This release featured the band's versions of songs by artists as diverse as Nico, The Durutti Column and Blue Oyster Cult. In 2006 the band released their third full-length Espers II on Drag City Records.
Their fourth album, III, was released on October 20, 2009.
