Unknown includes drum and bass, rave and EDM, deep and original bass, experimental electronic ambient, and generally has an industrial tone. CERN is the creator of the internet, originally for scientific research. Today, they conduct experiments using a super hadron collider, which is depicted in the cover of Unknown. Unknown represents the unknown elements of our universe, and incorporates themes from Buddhism and abstract scientific concepts. The album is the eighth in the series and, like most albums, was created during a creative spree in early 2016, following Fragments.
