Deep Elm Records have released a compilation of various bands that wield musical alchemy under the post-rock banner. There are some great tracks here - most notably from mainstays The Appleseed Cast - although SM advocates Dorena also rate a mention. Apart from that though - its pretty low on the ground for anything approaching good. Still, you can pick it up here for free - check it out for yourself.
Dorena -From The Window Of My Room
Goonies Never Say Die - Nothing Remains Forever Yet The Future Still Holds Hope
