I'll start his with fantastic score of the sleazy, sci-fi film 'La bestia nello spazio', also known as 'Beast of Space'. The below selection is a good overall representation of the music, however my favorite sequences take a turn into funk territory, breaking out some shameless grooves.

I've also included a piece taken from his score for the 1978 film 'Occhi dalle stelle', also known as 'Eyes Behind the Stars'. Eerie music! To the best of my knowledge, the soundtrack has yet to be released on CD.
