Roll Deep and Rob Da Bank have been added to the line-up for the upcoming Roundhouse Turning Point festival.

British grime collective Roll Deep and the Radio 1 DJ will perform on the Main Stage at the event - which takes place at London's Roundhouse venue - on September 18.

The acts will be joining the likes of 'I Need You Tonight' hitmaker Professor Green and MC Ms. Dynamite at the festival, which celebrates fledging talent within the UK music industry.

Mercury Music Prize-winning hip-hop artist Ms. Dynamite is to return to the venue in Camden, north London, for a "homecoming" gig after a break from the limelight.

She said: "What's unique and super exciting about this festival is that it's all arranged and totally done by young people. I'm really excited to just be getting on stage!"

Headliner Professor Green recently revealed having 'Smile' singer Lily Allen - who features on his new track 'Just Be Good To Green' - perform alongside him at London's Wireless festival in July was the "maddest" day of his life.

He explained: "She couldn't be around for my set at Glastonbury, but we did the Wireless festival in London this month, which was phenomenal. It was nuts. It was the first time we had performed 'Just Be Good to Green' together live. It was the maddest day of my life."
