UnderPurple is a 70x100 cm (27x39inch) poster of Deep Purple’s genealogical tree, pictured as an Underground Map. All record, formation or reunion is represented and each underground line corresponds to every artist who has been part of the Deep Purple band, even if for just one album from 1960 to 2003. 
A clear and simple picture that will guide you through the history of Hard Rock, of the band itself and of every single component : Rainbow, Black Sabbath, Whitesnake and any other band related to the Deep Purple.
