Annie has got big BBC Introducing announcement to make: she's on the look out for some of the UK's hottest new artists - tune in to find out all about it.
And she's enlisted the help of Sheffield producer Walter Ego to provide this week's guest mix. Expect a right little bump 'n' grimey 2-step party mix.
There's also loads of new music from Skrillex, 12th Planet, Alex Metric and These Bright Machines. Plus all the usual dubstep, urban and bass-o-tronic music from Radio 1's First Lady, Annie Nightingale!

Alex Metric - Prophecies (Annie N Edit)
