Primal Scream and Belle & Sebastian have been announced as headliners for London's OnBlackheath Festival, Gigwise reports.

The city festival takes place - as you might have already guessed - on Blackheath Common, in September. The headliners will be joined by the likes of James, Roisin Murphy, Hot Chip, Squeeze, Lonelady and Soak, Gigwise said.

Meanwhile, Heavenly Records DJs will be back to curate the second stage, and NTS Radio will curate the festival's second day. There'll also be pop up entertainment, interactive street theatre, a silent disco and a food stage.

There's set to be a load more artists announced for the festival, but the eight acts unveiled are enough to give you a taster of what to expect, Gigwise said.
