As a way of creative recharge, I've been immersing myself lately in the music of Sigur Ros, an Icelandic band best known for their elegant and enigmatic sounds. You can find their music under rock, but I'm not sure that category does this group justice. There's something deeper going on under the surface as any viewing of their new documentary will reveal. This is a band that serves as both sage and priest for any creative soul looking to make art from the heart of authenticity.
