In an entirely new concept, Speight's Summit and rock band, I Am Giant immortalised the last Big Day Out in Auckland by filming and editing an entire music video in one day.

Twenty crew worked tirelessly from 7.30am - 5.30pm filming thousands of festival-goers. The 6098 frames were cut and edited at Mount Smart Stadium before the final product was rushed over to the stage and shown to the crowd as the finale to I Am Giant's set at 7pm.

Director, Greg Page from Fish and Clips says "I've always loved animation, and I love shooting rock clips.

This was a mad combination of both and the coolest thing was; we did it for real, using old school techniques and thousands of enthusiastic fans. I was in a daze as I stood under the big screen with the band and watched the clip play for the first time. Rock and roll at its best."

I Am Giant's 'Purple Heart' video will be available online for people to view on the Summit Facebook page, facebook.com/speightssummit where there are FREE downloads of the 'Purple Heart' track available and those lucky enough to make the cut will also be able to tag themselves in it.
