The perfect gift for baby Heather and her two mommies

Do you like Bjork? Do you have/know any babies?

Rockabye Baby produces lullaby versions of popular rock music -- what they like to call "cherub rock for a new generation" but I like to call hipster muzak -- arranged for the gentle sounds of glockenspiel, vibraphone, mellotron, harp and bells. Their upcoming releases include "oh so quiet" lullaby renditions of Bjork hits. The tunes are, well, lulling, and the marketing copy is, um, loving:

Love. No one can quite express it like Bjork. Love for her children. Love for her homeland. Love for the world. All is full of love. No matter what she's working on, you can be certain that the final product is full of the most beautiful and lush sounds found on this or any other planet. These instrumental lullaby renditions of some of Bjork's most cherished songs are an extension of the musical world she has created. This is a hidden place for your child to dream and escape, and it's oh so quiet.

Listen to sample clips here. Other Rockabye releases include baby-proof versions of No Doubt, Coldplay (I know, redundant), Metallica, Radiohead, Nirvana, Led Zeppelin and the Ramones ("Does your child need to be sedated?").
