Kristín Anna Valtýsdóttir (born 5 January 1982), also known as Kría Brekkan, is an Icelandic vocalist and classically trained multi-instrumentalist.

While in the studio, Eyvind Kang heard her piano playing and asked if she'd perform solo at The Stone in New York City.

On April 16, 2006 she performed at The Stone, appearing for the first time as Kría Brekkan, with Avey Tare of Animal Collective, playing grand piano, guitar and singing.

In late 2006, Kristín acknowledged that she had left múm in the beginning of that year, and published an open letter briefly describing her thoughts on the matter.

[1] Kristín Anna appeared on the cover of Belle & Sebastian's 2000 Fold Your Hands Child, You Walk Like a Peasant LP with her twin sister, Gyða.
