Swedish DJ Avicii thanked his Belfast fans for being with him for his last weekend of shows before his imminent retirement.
Back in March the one-man hit factory announced his retirement and with it Belfast would be among his last.
The announcement meant an invitation to fans from around the world to descend on Boucher Playing Fields to join in the celebrations.
The 26-year-old urged fans to make his final shows "go out with a bang".
And they delivered.
Avicii's performance was the climax to a fantastic second day with Jess Glynne, Duke Dumont, Galantis, SEEB and Zak Abel thrilling the crowd.
The Swedish DJ superstar whipped festival goers into a frenzy on Friday as he brought the two-day event to a electric close.
His fans had been queuing for hours to get the best spot to see the DJ's penultimate show.
And they weren’t disappointed as the he played hit after hit including Waiting For Love, Levels and the crowd favourite Wake Me Up.
Avicii - aka Tim Bergling - thanked his fans.
He said: “Thank you for being with me on my last weekend of shows. You are amazing."
Avicii followed rock legends the Red Hot Chili Peppers who headlined the first night of the two-day event.
The Chilis thrilled the crowds with their classics including Give It Away, Can't Stop and Under the Bridge.
Tennent's Vital boasts the biggest festival stage in Northern Ireland measuring 60m x 40m.
And with thousands of music-lovers descending on the playing fields it is well equipped with the Tennent's bar - which has the equivalent of 23 bus lengths of counter space, organisers claimed.
The RHCP were joined by Fall Out Boy, Cage the Elephant and Otherkin.
The Red Hot Chili Peppers last played Belfast as part of the MTV Europe Music Awards in 2011.
They have sold over 60million albums and have six Grammy Awards to their name.
