A statement from Bowie was read out on Saturday at a fundraising event for the Terrance Higgins Trust in a bar in Denmark Alley, London.
It read: "This city is even better than the one you were in last year, so remember to dance, dance, dance. And then sit down for a minute, knit something, then get up and run all over the place. Do it. Love on ya. More music soon. David"
Bowie's spokesperson confirmed to the NME that the singer had written the statement.
The Next Day, which Bowie released in March 2013, was recorded in great secrecy, with the singer having to change studios after rumours leaked that he was making new music. The record went on to top the UK charts and peak at number two in the US Billboard charts.
Many fans hoped that the new material would encourage Bowie to perform live for the first time since 2006, but he is yet to announce any plans to tour and didn't even appear at the opening of his V&A retrospective, David Bowie Is. When he won Best British Male at the Brit Awards in February, he sent Kate Moss to collect the award for him, with the speech: ""I'm completely delighted to have a Brit for being the best male - but I am, aren't I Kate? Yes. I think it's a great way to end the day. Thank you very, very much and Scotland stay with us."
