Definately sounds like Pendulum, but there are so many remixes these days it's hard to tell. I use a service on my mobile phone called Shazzam. All you do is dial the number, listen to the instructions, then hold the phone up to the music for 10 to 20 seconds. The service automatically hangs up when it's heard enough and texts you the artist and track. It works brilliantly. If you want the number just post something on my board.
