Drum roll please ... Beware of Mr Baker, a biopic of Cream drummer Ginger Baker, has taken the grand jury prize for documentary at SXSW. Jay Bulger's film shared the festival's highest prize with Adam Leon's Gimme the Loot, which took the grand jury prize for narrative fiction for its depiction of a pair of lovable graffiti artists facing off against their rivals on the streets of New York.

Both films earned positive reviews after their world premieres at the festival this week. "Like the graffiti art it documents, it's a lovingly handmade affair," said Indiewire's Eric Kohn of Leon's film. The Hollywood Reporter's John DeFore described the Baker documentary as "an affectionate but unfawning portrait that finds the drummer of Cream still keeping the beat despite hardships both institutional and self-inflicted". Bulger's film follows the drummer from his drug-addled days in the Eric Clapton-fronted supergroup, through his work with Afrobeat legend Fela Kuti, to his current past-time – raising polo ponies in South Africa.

Other winners at the awards ceremony in Austin included Bay of All Saints, Annie Eastman's film on Brazilian slum life and winner of the audience award for documentary, and Eden, a dark drama about a kidnapped New Mexican teenager, which won the audience prize for narrative fiction. Eden's star, Jamie Chung – a graduate of The Real World reality TV series – was given special recognition for her performance by the jury, alongside Besedka Johnson and Nico Stone, who appeared in Starlet and Booster respectively.

"It's been amazing this year to hear over and over again about the high range of quality across the board," festival producer Janet Pierson told the Hollywood Reporter. "SXSW is a special moment for the creative community to both inspire and be inspired."
