British Sea Power, the Holloways and Micah P Hinson have been added to the bulging line-up for the live music segment of the U.K.'s second annual Great Escape Festival.

They join a previously-announced bill of 150-plus local and international acts, which include Britain's Magic Numbers, Rakes and Mumm-Ra, Brazil's CSS, America's Willy Mason, and South Africa's Springbok Nude Girls.

The event will take place May 17-19 across 20 venues in the coastal town of Brighton, south east England.

Telecoms giant T-Mobile is partnering the music fest through its Street Gigs venture, which promises to introduce secret performances in unusual locations across Brighton.

In recent months, T-Mobile has hosted "street gigs" in London's Natural History Museum with the Strokes, featured British urban artist the Streets in a Lighthouse, and chart-topping British-based pop singer Mika in a Circus Tent.

The Great Escape Festival is booked by Martin Elbourne, music director of Glastonbury Festival, and organized by Jon Mcildowie of British live entertainment group Barfly.

The three-day live music itinerary is complemented with a daytime industry convention, which will cover such topics as cracking the Japanese market, the state of U.K. hip hop and developments in the digital music and media world.

As part of the convention program, Radio 1 DJ Rob Da Bank will conduct a keynote interview with veteran producer and club DJ Norman Cook, aka Fat Boy Slim.
