Cinevox Record has released the new editions of four cult soundtracks from its catalogue. La morte bussa due volte by Piero Umiliani, Perché si uccidono by Il reale impero britannico, Il Gatto by Ennio Morricone and Non ho sonno by the Goblin. All soundtracks were remastered. La morte bussa due volte includes one previously unreleased suite. It is a seven minutes lasting track which was probably created with a promotional purpose when the movie was released.
