The free bash was one of the biggest parties of the year

Katy Perry brought the celebrations for the Big Weekend music festival to an end, with acts praising the Glasgow crowd for creating an "incredible" atmosphere. Some of the biggest names in music took to the stage over the weekend-long event organised by BBC Radio 1. Coldplay, One Direction, Calvin Harris and Kings of Leon were among the acts who entertained the crowds at Glasgow Green. Kings Of Leon opened the final day performing favourites such as Use Somebody and Sex On Fire, with an impromptu appearance by Coldplay's Chris Martin joining the band on guitar

Also on the main stage over the weekend were Paolo Nutini, The Vamps, Jake Bugg and John Newman. Rita Ora, Lily Allen, Bastille, Pharell Williams, Ed Sheeran, The 1975 and Tinie Tempah completed the line-up. Love Me Again singer Newman said: "I've played Glasgow and I've got a weird curse about travelling to Glasgow where my bus breaks down or we're always late or something, but we always manage to get here, and every time we do get here you know it's always an incredible gig, so thank you to Glasgow." Radio 1 DJ Scott Mills said: "I think it's been my favourite Big Weekend and I've done a lot. It's because the crowd is so receptive to anything. "I think generally everything I do in Scotland is always good. I always say this about the student gigs. Last freshers I did Stirling, Aberdeen, both Glasgow unis, and Edinburgh, and they were the best student gigs that I've ever done. You just can't get a better crowd anywhere." Up to 50,000 people attended the free music festival over two days, with other perfomances on the In New Music We Trust stage coming from a number of acts, including Kasabian, Klaxons, Twin Atlantic and Sam Smith. Jamie Reynolds, bass guitarist of Klaxons, said: "It's just awesome. It's fantastic to be here in Glasgow, you know it's always a fantastic crowd in Glasgow, we love being here, so it's an all round winning situation today." Jason Carter, head of popular music, live music and events at the BBC, said: "The atmosphere yesterday was electric and there's a lot of very young people having the time of their lives, you know the concert was for free which makes it even more special in terms of atmosphere, so we always find when we come up to Scotland that it's one of the best audiences and reactions. "This venue in particular has a kind of amphitheatre around the main stage so it feels quite intimate for the artists. Certainly a lot of the artists have fed back and feel that they are playing in an intimate environment even though there's 25,000 people there.
