I got the Italian Language Superlearning tape 2 years or so ago. I've only really fully listened to the first Unit of it. It's Basic Phrases. If, I remember, the subsequent Units build on the previous units. I was mildly successful with the Unit 1 tape. That was before I really understood how to get into the AL State. When I get back home, I intend to PR Italian language and grammar books, and then will activate by listening to the SL tape series through in order. It seems to work for me so far, really.
