Metallica have had their songs reworked as lullabies for children.

In an album entitled Lullaby Renditions of Metallica, tracks such as 'Enter Sandman' and 'The Unforgiven' have been recorded with the unusual twist, for Baby Rock Records.

The album, which is out on August 29, is only the start for infants. Coldplay, Radiohead, The Beatles and Nirvana are among bands whose songs will be reworked by the label.
