It’s 25 years since the release of Kylie Minogue’s first single, Locomotion. To celebrate, the star has been holed up in London’s Abbey Road studios re-recording some of her hits, which will be released over the course of this year digitally. Social media is heavily involved in the campaign. The first track – an acoustic version of 1992 track ‘Finer Feelings’ – will be made available as a video today, but only if 25,000 fans tweet the #k25fans hashtag once the campaign goes live at 5pm. It’s the latest example of a ‘tweet to unlock’ digital campaign, although the nature of EMI’s initiative goes further than previous examples that have focused on a single track, rather than a series of releases.
