Mark Ronson is no stranger to collaborating. The producer has worked with Amy Winehouse, Paul McCartney, and Bruno Mars, just to name a few—and now he’s lending his talents to the Grammy Amplifier organization to work with some new musicians: aspiring ones.

On Tuesday, Ronson was named ambassador of the Grammy Amplifier, a mentorship program that pairs established musicians—this year’s lineup includes Ronson, Ziggy Marley, the Band Perry, and Allen Stone—with 25 artists.

Three of those 25 will ultimately be chosen to receive one of three grand prizes: a recording session with a Grammy-winning producer, a music video directed by a big name, or an opening slot on a tour for a well-known artist.

Artists can begin submitting their tracks now on the Grammy Amplifier website for a chance to be one of the 25 finalists.
