Very nice. Giallo circa '71 practically bleeds from these tracks, whether or not it's an element of the film! Johnnie To's pictures from the last decade or so, from THE MISSION onwards (and probably a few before that), have some of the most thoughtfully integrated scoring I've ever seen in Hong Kong pictures. The man has an ear for cool. It'd be nice if this turns up on ITunes at some point.
