O.R.k. – the group consists of: Italian vocalist, producer and award-winning composer of film music Lorenzo Esposito Fornasari a.k.a LEF (lead vocals), Pat Mastelotto of King Crimson (drums), Colin Edwin of Porcupine Tree (bass) and Carmelo Pipitone of Marty Sui Tubi (guitars). How do you define O.R.K. music? According to Frank Zappa's humorous sentence, you can't. It would seem that it is impossible to harmonize Lef's powerful vocals, Pipitone's energetic riffs with inventive Mastelotto rhythms and Edwin's characteristic tones. O.R.K music cannot be compared to anything else. This is proven on records and will certainly be confirmed during a concert.
