Limited edition of 3000 individually numbered copies on yellow & black marble coloured 180-gram audiophile vinyl. L.D. 50 is the debut studio album by Mudvayne, the American heavy metal band that is known for their sonic experimentation and horror-styled appearances. The album was co-produced by none other than Garth Richardson and Shawn "Clown" Crahan of Slipknot. For the album, they experimented with a ragged, dissonant sound; a sound collage prepared specially for the album that was used as a series of interludes. It spawned three singles, "Death Blooms", "Nothing To Gein", and one of their biggest hits to date: "Dig". In the year of it's release, the album peaked at #1 on the Billboard Top Heatseekers chart and #85 on the Billboard 200. It gained more critical praise over time and was named one of the twenty best metal albums of 2000 by Metal Hammer magazine.
