Throttle – What’s That Sound (Live Mashup) Brian AndersonMonday, September 16, 2013ElectroReviews0 Comments4452 views After hearing many poorly made bootlegs and mash ups it’s really gratifying when an amazing one comes up. Throttle‘s mashup “What’s That Sound” combines many sound bits from many artists such as: Zedd, Knife Party, Skrillex, Krewella and Mackelmore. The transitions are nearly flawless throughout the track and at the end it leaves the listener wanting more. Watch as Throttle maneuvers around a launch pad and a keyboard in this sweet live mashup video. Madeon might have to watch out, this might be one of the best of all time.
