Jack White and company claim that their new LP Lazaretto is a technically mastered vinyl masterpiece, loaded with some amazing feats of physics.  The album features an inside to out groove (has been done), an outer looped locked groove at the edge, and a hidden track that plays under the label, it is mastered at 3 speeds: 45rmp, 33.3 rpm, and 78rpm, has a pot luck double groove on side B (been done before), features two matte vinyl finishes, and has an etched floating hologram of two angels at the outro band.  You must see this video if you love vinyl.  Kudos Jack !!!
