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;[2] a CD edition was reissued in 1985 through Enigma Records,[3] and a remaster in 2008 through Belle Antique.[4] Holdsworth’s band consists of drummer and pianist Gary Husband, bassist Paul Carmichael and singer Paul Williams, with whom Holdsworth had worked in Tempest. A previous solo album, Velvet Darkness, was released in 1976 without Holdsworth's consent,[5] therefore making this (in his view) his first official solo release. Many tracks from Velvet Darkness were refined, re-recorded and retitled for I.O.U., whilst "The Things You see" takes its name from an earlier album of the same name, made in collaboration with keyboardist Gordon Beck.
