I.O.U. is the second studio album by guitarist Allan Holdsworth, released in 1982 through Luna Crack Records/I.O.U. Records originally on vinyl; a CD edition was reissued in 1985 through Enigma Records[3] and a remaster in 2008 through Belle Antique.[4] A previous album, Velvet Darkness, was released in 1976 without Holdsworth's consent,[5] therefore making this (in his view) his first official solo release. Furthermore, many tracks from Velvet Darkness were remade and retitled for I.O.U..
