I was never a great fan of the 5th Doctor era, but l have to admit that his final story is one of the greatest adventures from the 'classic' series. The soundtrack is equally amazing. Its not music to tap your toe to and it isn't particularly tuneful, but it is dripping with atmosphere. This is classic 80s electric music to work to if you are creative in anyway and this can really set your mind into dark imaginings. It serves also as a reminder of a time when the soundtrack wasn't as intrusive as it is now.
I said before, don't expect to dance to it unless you're very strang indeed.
