Michel Thomas is a linguist with fifty years of teaching experience. He developed a new way of learning languages, that emphasises on making the language seem easy for the student. The method focuses on making the course fun, with no memorising, no physical or mental homework, pretty much a very unconventional way to learn. What is even better, is that there are several languages that you can try out.
His recordings on language can be found on a variety of torrent websites. I would suggest that you use demonoid, which is an excellent source for his recordings. Alternatively, you can also buy the audio books from Barnes and Noble.
