Uneven Structure is a progressive metal band based in Metz, France. They play a style of post-metal which is heavily influenced by the Swedish extreme metal band Meshuggah. The band blends polyrhythmic passages and extremely low tunings with a heavily layered production style and ambient soundscapes. They are often categorized in the djent movement due to the Meshuggah-like guitar tone they often employ. The band was formed after the split of Longchat, a band which featured Igor Omodei and Benoit Friedrich.
