The group Espers plays psych-folk. At least that's the category some have placed them in, a category that hasn't had much use since the late 1960s when groups such as The Incredible String Band were making a kind of poetic, experimental, acoustic psychedelia. Now, in 2004, we find ourselves in the midst of a psych-folk revival. The six young Philadelphia-based musicians of Espers visit with host David Garland, and perform several of their moody, subdued-but-intense songs in the WNYC studio. After their live set, Espers become guest DJs, sharing old and new recordings they love.
