Mobile operator Orange UK has given more details on the “hologram gigs” to be held in the UK to promote its new Monkey music service.They’ll take place in five shopping centres around the country in September and October, and will feature hologrammatic versions of Pixie Lott, N-Dubz and Tinchy Stryder performing. Free Monkey SIM cards will be available at each event, plus £10-off vouchers for the pay-as-you-go handsets required to use the service. Monkey launched earlier this year, and is an exclusive partnership between Orange, UMG and Channel 4.
