Avant-rock drummers Greg Fox (Guardian Alien, Liturgy, Zs) and Child Millions (Oneida, Guy Forever, Folks of the North) came together in 2014 for the improvisatory cooperation Fox Thousands Duo. The duo’s long-form classes range from loud, percussive freakouts to calmer, meditative drones. Excitement Jockey released the duo’s debut documenting, Lost Period, in 2015.
