Emeli Sande and Professor Green surprise at 1Xtra Live
Emeli Sande and Professor Green were the surprise guests at the second leg of BBC 1Xtra Live.
They were brought on by Naughty Boy, who opened the gig at the Hammersmith Apollo in London on Tuesday night.
2 Chainz, Fuse ODG, Angel Haze and Sean Paul also performed to the packed out crowd.
"I always get a bit scared when it is a big event but afterwards I am so excited because the way the crowd reacts," said Naughty Boy.
"I feel like I have given them a show and that's all I want to do really.
"Everyone that came out is a friend and I am a fan of and people who've been part of the album."
Headliner Sean Paul seemed to be the favourite with many of the fans at the west London venue.
"He's just amazing, the energy was great, everyone was dancing, it was just so much fun," said Ellen Hamblin from Derbyshire.
The Jamaican dancehall and reggae star said he was delighted to be back performing for BBC Radio 1Xtra.
He spoke before his headline set, which saw him bring on US rapper 2 Chainz for one track.
"1Xtra I have been down with from the very beginning and I remember early shows from the early, early years," he explained.
"A station like 1Xtra reminds me that we are growing bigger year after year."
Relative newcomer Angel Haze said it was great to be part of the event.
"I'm buzzing right now, it's crazy," she said after finishing her set.
She played tracks from her debut album, which is due to be released early next year.
"It's kind of scary but at the same time I am so proud of what I have done, what I have made, I just want the rest of the world to enjoy it."
The American MC picked up a few new fans at the gig.
"We hadn't really heard much of her [Angel Haze] before, she was really good, and it's nice to see something new," said 25-year-old Rosie Whitham.
1Xtra Live is now in its sixth year.
Monday night saw performances from Katy B, Chase & Status and Sub Focus.
On Wednesday night, BBC 1Xtra Live heads to Liverpool where Robin Thicke, Iggy Azelia and John Newman will perform.
