On April 29th, Record Store Day, Soundgarden will release a limited edition vinyl collection of the demos for the band's 2012 album, King Animal. This will mark the first time these early recordings of tracks from the CD have been made available. According to Blabbermouth, the six-song package will be pressed on 10-inch pink vinyl and will also include a free digital download card. The demos were recorded by both singer Chris Cornell and the entire band at studios in Los Angeles and Seattle.
