Chicago's Russian Circles have always experimented with music's darker side. On Enter, the trio crafted metal-tinged, moody instrumentals, but managed to break the spell for few a moments of subtle beauty. On their new record, Station, the band have abandoned all hope. There's very little clearing in these threatening skies—everything is more aggressive, more sinister. The fearless will be up front, praising the band with a slow, heavy headbang.
