Chicago instrumental rockers Russian Circles return with their fourth full-length Empros on October 25th – and if the first single "Mladek" is any indication, the band still proudly sports their progressive, metal sound. Kicking off with a melodic guitar riff, the cut quickly grows into a much larger, explosive track. Apparently the band named the track after their European driver, Tomas Mladek, because he's "awesome," says a band member. "He's a wealth of knowledge on European history, a towering tattooed hirsute Eastern European brute, a lover of '90s hardcore ice cream bars, and proud fetishist with more bizarre sexual proclivities than any other person I know." Awesome indeed, and you can download the song for free here.
