It's such a simple idea it is amazing no-one has thought of it before - Musicdocs - a whole day festival dedicated to the "rockumentary".

That sort of eureka moment must have greeted Peter Whitehead's first music video for the Rolling Stones when it arrived in the offices of Top Of The Pops.

Whitehead - the "cineaste" behind 1960s scene-documents Tonite Let's All Make Love In London, Wholly Communion and currently unavailable Stones doc Charlie Is My Darling - was the headline guest and a perfect choice for this celebration of music and film.

He was engaging, genial and full of compelling stories, while at the same time self-deprecating, appearing to regard some of his greatest works as happy accidents.

The discussion barely covered a few years of his amazing career, giving the feeling the film-maker could be a repeat visitor to future Musicdoc events.

While Whitehead talked about the genesis of combining music and film, the previous talk focused on a pair of musicians who had begun to explore the world of cinema.

It was a shame the festival's screenings programme didn't feature Bob Stanley and Paul Kelly's Finisterre - A Film About London, or their document of the parts of Hackney Wick being transformed by the Olympics. The pair sold their films so well that the brief snippets screened during the talk didn't quite feel long enough.

Judging by this first event, Musicdoc could well have legs - here's hoping it's back bigger and better for 2012.
