Salem - Water EP (Merok) 7"
There is also this. A compilation of music from Dario Argento's films including tracks from Goblin, Ennio Morricone, Claudio Simonetti, Keith Emerson and Signor Wolf.
A rather marvellous compilation no less but the limited nature of Salem and House Of House vinyl releases they are the ones that will no doubt form the basis of a decision. Hmmmmmm.
