Harry Styles is using social media to tease details about his upcoming solo music project – which is apparently called ‘Sign of the Times’ and will be released this time next week.

The former One Direction singer is the fourth ex-member of the band to reveal solo music project, with new father Liam Payne now the only one who hasn’t revealed anything yet in the way of music.

‘Sign of the Times’ – or ‘SIGN.OF.THE.TIMES’, as the 23 year old has been plugging it – will come out on April 7th, as he wrote “SIGN.OF.THE.TIMES // 7.APRIL.17 //,” alongside a picture of what is presumably going to be the artwork.

It’s as yet unclear whether this is a single or an album (most likely the former, as industry tradition dictates) but there will definitely be a live performance of it the following week, when Styles performs on ‘Saturday Night Live’ the following week (April 15th) in what will be his debut solo television performance.

It’s set to be a busy year for Styles, as he’s also set to make his acting debut in Christopher Nolan’s World War II epic Dunkirk when it hits cinemas in July. Audiences got to see the breathtaking scope of the project at a preview at CinemaCon in Las Vegas earlier this week.

According to music industry news site HITS Daily Double, the material that Styles has been working on sounds like a “celebration of all things ‘70s British rock… The lead single, which could come out as soon as late April or early May, sounds like it would be a smash in any decade.”

Fans were incredibly excited by the Instagram reveal, with 280,000 people liking his Instagram post in just 30 minutes, with another 33,000 comments left underneath.

It comes just a few days after Zayn Malik, who of course left 1D two years ago just before they went on hiatus, promised fans that new material following up his debut solo album Mind of Mine last year was on its way.
