What is "hipgnosis"

Hipgnosis was an English art design group based in London that specialised in creating cover art for the albums of rock musicians and bands. Notable commissions included work for Pink Floyd, T. Rex, The Pretty Things, UFO, 10cc, Bad Company, Led Zeppelin, AC/DC, Scorpions, Yes, Def Leppard, Paul McCartney & Wings, The Alan Parsons Project, Genesis, Peter Gabriel, Electric Light Orchestra, The Police, Rainbow, Styx, Pezband, XTC and Al Stewart.

Hipgnosis consisted primarily of Cambridge natives Storm Thorgerson and Aubrey Powell, and later Peter Christopherson. The group dissolved in 1983, though Thorgerson worked on album designs until his death on 18 April 2013, and Powell works in film and video, most notably with Paul McCartney, The Who, and Monty Python's Flying Circus and is Creative Director for David Gilmour and Pink Floyd.
