Múm- We Have A Map of the Piano

Múm is an experimental pop-electronica group from Iceland that released "We have a Map of the Piano" on their second album titled Finally We Are No One in 2002. The track starts with a mysterious percussion and progresses to what almost sounds like a classical piece. The beat is ambient and downtempo combined with delicate and whispery female vocals.

Sounds similar to Aphex Twin,  Cocorosie

Happy listening :)
