Superproducer Mark Ronson is set to share the secrets of his success with aspiring musicians as the ambassador for the 2015 Grammy Amplifier online singing contest.
Reggae star Ziggy Marley, country group the Band Perry and singer/songwriter Allen Stone will help to scout for talent and select the 25 finalists for the Recording Academy organisation's third annual competition, while the Uptown Funk hitmaker will whittle down the group to the final three and serve as their mentor to help set the budding artists on the path to stardom.
The top three will then be awarded one of three big opportunities: a recording session with a Grammy-winning producer, a video shoot or a set at an upcoming music festival or an opening slot for a top artist.
The programme opened for submissions on Tuesday (27Jan15) and winners will be announced at the Grammy Amplifier showcase at the South by Southwest festival in Austin, Texas in March (15).
Previous celebrity participants include David Guetta, Ariana Grande, Kendrick Lamar, Hunter Hayes and Robert Glasper.
