IFC is going to be holding a video contest for Portishead..I'd post the link, but I cn't seem to find it yet. But the contest has just been posted- they still haven't posted any rules or info yet...as soon as I have that I'll pass it on.
On another note..we found some interesting information on the Radiohead contest today. The way this contest is supposed to work, everyone can submit videos up until June 2nd. Aniboom picks 10 semifinalist but you still can upload a whole video for consideration in the contest after the semi-finalists are pciked, which is what we are doing.
But check the Rolling Stones link..it sounds like this contest is giving some contestants and unfair advantage (review comments section in article)
