Sunroof! was the new-millennium guise of U.K. guitarist Matthew Bower, a longtime veteran of the experimental noise-rock scene. Bower had begun his career with a short-lived band called Pure, which mutated into Total in 1982; five years later, Total transformed into the prolific Skullflower, which proved the best-known of Bower's vehicles. Skullflower turned Total into a largely solo side project with a free-improvisation bent, which eventually became Bower's main focus. The Puff Daddy-affiliated R&B group Total laid exclusive claim to the moniker in the late ‘90s, at which point Bower retired it and continued on -- in much the same style -- under the new name Sunroof!. Sunroof! kept much of the monolithic, droning noise for which Skullflower was known -- informed principally by psychedelia and early industrial music -- but also followed the more ambient, free-form direction of early-'90s Total and late Skullflower. With Sunroof!, Bower also seemed to make more conscious attempts at sonic diversity, varying the moods of his lengthy pieces and incorporating hints of British folk and ethnic music while upping the vintage electronics and found sounds.
