The latest publication from the Slavs and Tatars artist collective is a fascinating, humorous consideration of pedagogy, language mysticism and the written word, all pivoting on a single phoneme: "kh." Part of Slavs and Tatars' Faculty of Substitutioncycle, Khhhhhhhlooks at the phoneme's recurrence across Semitic, Cyrillic and Arabic alphabets, and its mystical, literary and political applications: Kabalah, gematria and Russian Futurist Velemir Khlebnikov's exploration of phonemes and his Futurist "zaum" language. Parts of this project were exhibited at The Museum of Modern Art in New York in 2012, in the Museum's Projectsseries.
