Rough Trade opened its first shop in West London 40 years ago this autumn. The record store and label will be celebrating its 40th birthday with a special concert at London Barbican on 22 October featuring three new collaborations between some of the label’s earliest artists and “similarly adventurous musicians who’ve emerged in more recent years”. Rough Trade veterans The Pop Group will be collaborating with Protomartyr; Scritti Politti (first signed to the label in 1979) with Hot Chip’s Alexis Taylor; and John Grant with new project Wrangler featuring Stephen Mallinder of Cabaret Voltaire (whose Extended Play EP was the label’s first UK release).
