German magazine publisher Axel Springer has launched an iPad app for its Metal Hammer brand tracing the “History of Metal”. The £3.99 app promises “An all-embracing overview concerning the evolution of hard rocking music”, including video interviews, archive articles, interactive timelines and CD reviews with audio samples and iTunes purchase links. “You really think that Metal is solely black? Well, your are wrong. There is hardly another music genre that invokes so many different influences and can look back on such a long and exciting history,” explains its App Store listing.
