I.O.U. (album)

I.O.U. is the sixth studio album by British guitarist Allan Holdsworth, released in 1982. It is considered a significant album in the jazz fusion genre, notable for its complex harmonies, improvisational solos, and Holdsworth's innovative use of legato guitar techniques.

The album features a quartet consisting of Allan Holdsworth on guitar, Paul Williams on vocals, Gary Husband on drums, and Jeff Berlin on bass. While Holdsworth is primarily known for his instrumental work, I.O.U. is unique in his discography for featuring prominent vocal performances throughout.

The album's title, I.O.U., is a play on words and reflects the band's dynamic. The songwriting credits are shared among the band members, contributing to a collaborative feel.

Tracks such as "The Things You See (When You Haven't Got Your Gun)" and "Letters of Marque" showcase Holdsworth's signature sound, characterized by sweeping arpeggios, wide-interval leaps, and a fluid, almost saxophone-like tone achieved through his unique guitar playing style. The album is widely regarded as a cornerstone of Holdsworth's career and a landmark achievement in jazz fusion guitar.
