Medúlla is the sixth studio album by Icelandic singer, songwriter, and musician Björk, released on August 30, 2004 by Warner Bros. Records and One Little Indian. The title derives from the Latin word for "marrow". The album is almost entirely a cappella and constructed with human vocals. Medúlla received two Grammy Award nominations and reached number one in several record charts. In celebration of Björk's mid-career retrospective at the Museum of Modern Art in New York, and the release of the Björk: Archives book, One Little Indian is reissuing the Björk vinyl back catalogue, and for an exclusive period the vinyl will be colored to the hue that personifies that album character.
