Kate Bush on her new album

In a rare interview, Kate Bush speaks to BBC Radio 4's Front Row about how she is writing songs for a new album, but does not know when they will be released.

Later this month Bush releases Director's Cut - a collection of reworked songs from her albums The Sensual World and The Red Shoes.

Her last album, Aerial, came out in late 2005 and was itself her first new release for 12 years.
