Elly Jackson, one half of electro-pop duo La Roux, says she's changing her voice for her forthcoming second album.
Their self-titled 2009 debut was typified by Jackson's shrill vocals.
Jackson and bandmate Ben Langmaid are writing material for the follow-up in between touring commitments.
She said: "The vocal style will be different, I've changed the way I sing. Not on purpose, it's just happened, seeing things I can do with my voice."
