Police are urging fans attending tonight’s DJ Hardwell concert to keep safe.
More than 11,000 people are expected at the event which is due to kick-off at 6pm at the Royal Highland Centre in Ingliston.
Police say they have been working with the event organisers and the City of Edinburgh Council to make sure the event runs smoothly.
Measures include high visibility uniform patrols and ticket-holders being searched by stewards with additional searches being carried out by the police if they feel it is necessarily.
Special drug patrols and sniffer dogs will also be going through the crowds.
Chief Inspector Graham McInarlin said: “Our message for tonight is clear - we want everyone to have a great night and enjoy the music and carnival atmosphere but make sure they do not behave in a manner that will not put themselves or others in danger.
“We will have large numbers of officers in place at the event to assist the stewarding staff who will be helped look out for anyone trying to bring drugs, alcohol or weapons into the venue.”
He added: “We would ask everyone in attendance to work with us so the concert is a safe and enjoyable event for everyone.”
