Coldplay's Chris Martin Debuts New Song at Apple Launch

Coldplay front man Chris Martin made a surprise appearance at an Apple convention in California on Wednesday evening (Sept. 1) surprising their attending employees by debuting new song 'Wedding Bells' as part of a short three-track set, reports NME.

The event was used by the consumer electronics company to launch several new products including music and social networking site Ping, which allows users to build friends and follow musicians. Martin, sporting a Flaming Lips t-shirt, was in good spirits as he took to the lone piano on the convention centre stage, and launched into his band's breakthrough 2000 single 'Yellow' before moving onto 2008's 'Viva La Vida.'

Initially planning to finish there, the artist was encouraged to continue and so finished with his new song. A concise, sombre ballad, it features Martin's trademark soaring vocal fluctuating between loud and quiet dynamics.

Upon introducing 'Wedding Bells,' Martin joked "this is a new song called 'Coldplay 2.6' and it has a lot of new features, it features seven different kinds of chords and even a new one that our closest rivals have no idea about," before nervously admitting "it could terribly wrong." However, judging by the warm applause received from his audience, including Apple CEO Steve Jobs, such an outcome didn't materialise. Coldplay are yet to announce when they're to return with a new album.
