Russian Circles is an American post-metal band based in Chicago, Illinois. The band was originally formed by childhood friends Mike Sullivan and Dave Turncrantz after their previous musical projects dissolved. After parting ways with their original bass player Colin DeKuiper in 2007, the trio was rounded out by Brian Cook. The band has gained widespread recognition based on a series of critically acclaimed albums and extensive international touring. Their name is taken from a drill exercise used in ice hockey, a sport Sullivan and Turncrantz grew up playing in their original hometown of St. Louis.

Post-metal is a music genre rooted in heavy metal but exploring approaches beyond metal conventions while being related to and similar to post-rock. It emerged in the 1990s with bands such as Neurosis and Godflesh, who transformed metal texture through experimental composition. In a way similar to the predecessor genres post-rock and post-hardcore, post-metal offsets the darkness and intensity of extreme metal with an emphasis on atmosphere, emotion, and even "revelation", developing an expansive but introspective sound variously imbued with elements of ambient, noise, psychedelic, progressive, and classical music, and often shoegaze and art rock. Songs are typically long, with loose and layered structures that discard the verse–chorus form in favor of crescendos and repeating themes. The sound centres on guitars and drums, while any vocals are often but not always screamed or growled and resemble an additional instrument.
