Russian Circles are an American instrumental rock trio from Chicago, IL. Their sound consists of expansive guitar sounds created by guitarist Mike Sullivan's extensive looping and layering (a sound which he accurately reproduces at live shows), as well as heavily rhythmic drums and crushing basslines. They feature the cinematic soundscapes common to post-rock, but are not afraid to keep some sections heavy with a capital H, and have plenty of rhythm changes. They formed in 2005, and self-released an eponymous EP, followed shortly thereafter by their full-length debut, ''Enter''. Russian Circles provide a sonic adventure that should be enjoyable for any fan of the genre.
