The rapper, Dizzee Rascal, is coming to Suffolk this evening.
20,000 people are expected for the Newmarket Nights event at the racecourse.

Newmarket javelin thrower Goldie Sayers says she's honoured to have been named as Team GB captain for next week's European Championships in Zurich.
The former Ely school pupil has struggled with a serious elbow injury since the Olympics two years ago, but made her competitive comeback recently in the Commonwealth Games.
“Having had a fairly nightmarish past 18 months - and not knowing whether I'd ever throw or compete again - getting back into the GB vest alone has been incredible.
To say captaincy is an added bonus, is a massive understatement."
Investigations have been continuing today to try and find out why a racehorse owned by the Queen and trained by Sir Michael Stoute in Newmarket tested positive for a banned substance.
In a statement the Queen's racing manager said it's thought Gold Cup winner Estimate failed a drugs test because some of her feed was contaminated.
Four more horses from different yards also failed the test.

A racehorse owned by the Queen and trained by Newmarket based Sir Michael Stoute has tested positive for a banned substance.
In a statement the Queen's racing advisor says it may have been caused by contaminated feed.
Four more horses from different trainers also tested positive.
Estimate, the racehorse owned by the Queen, helped her to make sporting history as she became the first reigning monarch to win Royal Ascot's Gold Cup.
"On Thursday 17 July the British Horseracing Authority announced that a number of post-race samples, obtained from recent race meetings, had been found to indicate the presence of morphine, which is a prohibited substance on race days. Five horses, under the care of various trainers, were affected.
I can confirm that one of those horses was Estimate, the five-year-old mare trained by Sir Michael Stoute and owned by the Queen. Initial indications are that the positive test resulted from the consumption of a contaminated feed product. Sir Michael is working closely with the feed company involved to discover how the product may have become contaminated prior to delivery to his stables."
