You ever hear a guitar riff so intoxicating you want everything else to go away so you and the guitar riff can be alone for all eternity? No? Well, how about one you just want to listen to over and over? Yeah, that might be more reasonable. Sofa Surfers, an Austrian electronic rock group, recorded the original “Can I Get a Witness” and brought this divine riff into the world. On the remix, Thievery Corporation cranks up the tempo and reverb, adding a harder conga-driven beat and dub atmosphere. That riff though. That riff.
