The cross platform 'On-line and On-tour' campaign, sponsored by Nissan's Qashqai, invites Metro readers and aspiring bands to upload original tracks for a chance to tour the UK with artist VV Brown.
The campaign was designed by Metro's in-house ad team, including the interactive microsite MEmusic, Metro's music and social networking site, as well as print adverts and editorials.
Five regional finals will be held across the country with five finalists playing at each event, selected by a panel of judges from Metro and Island Records, and voted on by Metro readers.
The winning act will also have their track recorded in a studio and distributed digitally.
Nissan Qashqai will offer Metro readers who are not in a band the opportunity to get involved, with a competition on the QashqaiIsland website, offering the chance to win a trip to Sydney to see Pearl Jam.
Jamie Walters, digital director at Metro, said: "On-line and On-tour fits well with Metro's young urbanite audience who love live music and interacting online.
"The bespoke cross platform campaign to promote the competition highlights the digital and in paper activity available to advertisers to reach Metro's young urbanite audience."
The competition runs until 19th October.
