Ace and Vis, aka The Troublemakers of Radio, are radio DJs and television presenters from south-east London. They met whilst studying at the BRIT School in London. Known as Ace and Invisible (Vis), after winning a gold Sony Radio Academy Award for their lunchtime show on BBC Radio 1Xtra in 2004, the two later co-presented BBC Radio 1Xtra's drivetime show from 4-7pm on weekdays, before moving to the 4-7pm weekend slot. They left BBC Radio 1Xtra in September 2012. They have also co-presented a show on the UK's Channel U TV (now Channel AKA).
