London's Idea Generation gallery, host for the recent Syd Barrett: Art and Letters exhibition, have just announced a pair of upcoming shows that will be of interest to Pink Floyd fans.

"Hapshash Takes a Trip: the sixties work of Nigel Waymouth" takes place between September 9th and October 2nd, 2011, and is a major retrospective of legendary British design duo Nigel Waymouth and Michael English, also known as Hapshash & the Coloured Coat. From the iconic UFO Club posters to pioneering fashion boutique Granny takes a Trip, Nigel Waymouth was omnipresent throughout London in the late 1960s. Nigel's psychedelic yet romantic Art Nouveau style, which he developed alongside Michael English, soon became a familiar trademark.

The exhibition will featuring original acetates, drawings, album covers, mind-bending psychedelic posters and personal photographs.

Storm Thorgerson: Big & Small follows, and can be seen between October 21st and November 13th, 2011. Widely regarded as the most influential and prolific designer of album artwork, Storm Thorgerson will be no stranger to Floyd fans. A conceptual study exploring the fundamental shift in record cover culture today, this new exhibition will explore the transition from vinyl to the tiny digital squares displayed on our MP3 players. Expect a series of ambitious installations and an exciting programme of events from the man behind some of the world's best loved and recognisable album artwork.

Idea Generation is at 11 Chance Street, London E2 7JB, and more information can be found at their website: gallery.ideageneration.co.uk.
