For several months, high-profile producer and DJ has presented a weekly program, dubbed Laptop Symphony, for Sirius XM. Here, he puts together a like-titled mix that acts as a permanent version of what a listener can expect to hear: an up-to-date cross-section of progressive trance and commercial dubstep and house -- or EDM ("electronic dance music"). Appearances come from the likes of ("Cloudburn"), ("Menage a Trois"), and ("Punk [Arty Rock-n-Rolla Mix]"), as well as himself.
