Uptown Funk hitmaker Mark Ronson has been announced as ambassador of GRAMMY Amplifier, an online music initiative aimed at mentoring emerging artists, and providing them the opportunity to 'elevate their careers by showcasing their talent'.

Ronson is part of a panel, including The Band Perry and Ziggy Marley, who'll vet talent via online submissions before selecting three winners who will claim one of three prizes: a studio recording session with a GRAMMY-winning producer; filming and starring in their own music video with a noted director; or securing an opening spot for a noted musician and/or at a music festival.
