This year's Record Store Day is April 21, 2012. In honor of the retail holiday designed to benefit music recorded on vinyl as well as independent retailers, a number of limited edition releases have been announced. Among those, Rhymesayers Entertainment (according to the official Record Store Day site) will release a 10" featuring Atmosphere as well as The Uncluded (Aesop Rock and Kimya Dawson).
The vinyl piece, said to be limited at 1,500 overall pressings will reportedly feature unreleased material by both RSE acts, as well as an audio version of "A Poop Story," told by Atmosphere's Slug.
