L.A.-based music company Mophonics is settling into their newest space, a massive Miami Design District warehouse shared with editorial company Lucha Libre. Michael Frick, executive producer and founder, explained the move. "We've been working with some producers and artists down there," Frick says, "It's kind of going to evolve into a full-scale post-production conglomerate." In addition to using the company's direct link to iTunes as a label for Miami-based talent, Frick counts further tapping the Latin market and giving Mophonics East Coast presence as additional motivations for the move. ...
