Last night at a concert in Leeds, UK, Yeezus contributor Hudson Mohawke dropped an unreleased version of Kanye West's love song to Kim Kardashian, "Bound 2." The three-and-a-half minute track only features Kanye's first verse, with some lines cut like "Rock Forever 21 but just turned 30," and a few added. It's also decidedly more atmospheric with an extended outro. Compare both below. The title of the Yeezus track, "Bound 2," suggests that there was at least one earlier version -- this could be the original "Bound."
