Charlotte Church has always done things her own way.
Moving from classical prodigy to pop maiden, the Welsh artist has recently found herself drawn to political activism.
Whether it's appearing on anti-austerity marches to chatting with Pussy Riot at Glastonbury, the singer has stuck rigidly to her beliefs.
This morning (August 26th) it seems that Charlotte Church took aim at Shell HQ. The singer performed outside the company's main London office, part of a week-long series of Titanic themed protests featuring a variety of guests.
Charlotte Church sang a version of 'Requiem For Arctic Ice' before plunging into 'This Bitter Earth'. Couldn't make it? Don't worry, the performance will shortly be made available as a free download.
Charlotte Church has uploaded her performance for SoundClound - and it's wonderful. Sparse, Erased Tapes style arrangements and a billowing vocal which moves between jazz, pop and classical.
