Jazz greats of the 20th Century are being brought back to the streets of London today through a collaboration between a University of Derby artist and a technical wizard. Renowned artist Professor John Goto's series of photo artworks West End Blues: Jazz Migrants in London 1919-1974 shows silhouettes of jazz musicians such as Louis Armstrong, Art Pepper and Sidney Bechet against the real London music spots they once played at. Mobile phone users can now bring those same silhouette images up on their phone's screen when they visit those London sites today, by using a mobile phone app(lication). For example, when standing outside the London Palladium their phone screen will show the silhouette of Louis Armstrong, as he appears in Professor Goto's picture: Louis Armstrong, London Palladium, 1932. The phone user can also access guided directions between sites, background information on the Jazz musician and hear samples of their work. Professor Goto worked on the 'Augmented Reality' project with Derby colleague Dr Matthew Leach. Both are part of the University's Digital and Material Arts Research Centre Their project uses a mobile phone application called Layar, which can be downloaded for both Apple and Android mobile devices.
