RJD2 likes to build sounds.

The musician has been making tunes for more than a decade: First as a DJ, then as a hip-hop producer, then as a solo artist (the Mad Men theme song is his "A Beautiful Mine"). Now, as part of the duo Icebird, he's taken his gearhead obsession — building his own modular synthesizers to make his music — further than ever.
