Got a few CDs on Beat Records: Fabio Frizzi's The Beyond, Zombi 2 and A Cat in the Brain; Francesco De Masi's The New York Ripper and Piero Piccioni's Una Tomba Aperta... Una Bara Vuota.
The Beyond is the best by far, I think; Zombi 2 is also good (although some of the "exotic" sounding tracks go on for too long), while A Cat in the Brain is only good when it has parts lifted pretty much straight from The Beyond/Zombi 2 (all 3 soundtracks share certain tracks), otherwise it's simply terrible. Crappy easy listening music.
The New York Ripper has a great atmosphere. Una Tomba Aperta... is a typical soundtrack in the sense that while there's nothing wrong with it, it simply isn't nearly memorable enough to be listened to on its own. I've heard it twice and will probably never listen to it again.
