DOCUMENTARY OF THE WEEK: 'The Great Hip Hop Hoax' Tells The Bizarre But True Story Of Scottish Rappers Silibil N' Brains

Apparently, being described as a pair of 'rapping Proclaimers' is not a good thing.

This was the discovery of Scottish duo Gavin Bain and Billy Boyd, who couldn't get anyone in the music industry to take them seriously, despite their creative energy and lyrical gymnastics - an oversight they were certain could be blamed on their Dundee origins.

Thus, they 'became' Californian hip-hop duo Silibil n' Brains, and, suddenly, queues were formed, girls were got and phone calls returned.

Silibil n' Brains were Dundee's answer to the Beastie Boys

It wasn't just Joe Public who was fooled. Jeanie Finlay's engrossing film shows the boys in full flow in front of a bunch of hardened Sony executives, and the pair sat on the books of industry veteran Jonathan Shalit.

A film which shares some themes with Bart Layton's masterful documentary 'The Imposter', 'The Great Hip Hop Hoax' raises questions of identity, and the question of why is authenticity so important, anyway, in the scheme of things?

'The Great Hip Hop Hoax' is in selected cinemas from today. Watch the trailer below...
