Underworld have been added to the bill for the 2011 Sonar Festival.

The Romford techno mainstays are among the first to join an intriguing line-up for the Barcelona event, with minimalist legend Steve Reich and dubstep supergroup Magnetic Man already confirmed.

A-Trak, Salem, Warp Records' Tyondai Braxton and Little Drago have also just been announced.

In other Underworld news, word has it they're set to work once again with director Danny Boyle, composing the soundtrack for his new stage version of Mary Shelley's Frankenstein at the National Theatre due to premiere in 2011.

Underworld have previously worked with Boyle on his films Sunshine, The Beach and perhaps most famously providing their track Born Slippy for his breakthrough flick Trainspotting.
