Relapse Records just re-released 6 Death albums on cassette, I scooped up the LEs of Scream Bloody Gore, Spiritual Healing, Leprosy, and Human. Love them, Slayer (who also just got some cassettes re-released), Rigor Mortis, Bolt Thrower, Morbid Angel, Metallica, and grindcore bands like Insect Warfare, Napalm Death, Phobia, Nasum, and Pig Destroyer.
