Reception

The AllMusic review by Paul Collins awarded the album 3 stars stating "Rypdal often alternates sections of great dissonance with near silence, or lonely sustained notes by just one or two instruments. It can have the sweeping starkness of a tracking shot over a fjord, but there's a certain coldness to it as well, and even confirmed fans of his jazz work may take a while to warm up to it."
