After the punk revolution of 1977, a number of bands inspired by the d.i.y. spirit and raw sound of punk were formed. However, instead of replicating the sound of the Sex Pistols, many of these bands forged into more experimental territory, taking cues from a range of artists and styles, such as Roxy Music, David Bowie (especially Low, Heroes and Lodger), disco, dub and Krautrock. The result was Post-Punk, a more adventurous and arty form of punk, no less angry or political but often more musically complex and diverse.
