This week, the free interactive app for iPad and iPhone by Blur became available on iTunes. The invention, rather unoriginally called 'Blur: The App', is complementary to the 21-piece retrospective, “Blur 21: The Box”, which will come out on 30th July. The app features rarities and unreleased music, demos, remixes, and archive footage of interviews and gigs. There are also photos, biogs, a band timeline, a full discography and videography, and a ‘gigography’ featuring every concert the Britons played, including set lists provided by setlism.fm. The app also synchronises the news appearing on the band's website, Facebook and Twitter pages, offering the possibility to share them on the different social networks.
