The prog rock supergroup O.R.k. consists of Italian singer, producer and film music composer Lorenzo Esposito Fornasari, drummer Pat Mastelotto (a member of King Crimson since 1994), bassist Colin Edwin (Porcupine Tree) and guitarist Carmelo Pipitone (Marty Sui Tubi). O.R.k. plays eclectic, technical music with a surrealist sensibility, firmly rooted in genre tropes; they have released four studio albums since forming in 2015, the latest of which is 2023's Screamnasium.
