Saturday, April 19 is Record Store Day, and we've got three very special limited edition releases coming out—Slipknot's Vol. 3: The Subliminal Verses on double clear vinyl; Opeth's Watershed on double green vinyl; and a one-sided 12" picture disc of Dream Theater's epic "Illumination Theory," from their self-titled album! So this week's Spotify playlist is devoted to those three releases (along with some extra tracks from Dream Theater). Listen now, and visit RecordStoreDay.com to find a participating store near you, so you can pick up these beautiful slabs of vinyl!
