One of the features that made Breaking Bad such a great series was its clever use of music to enhance the tone and atmosphere of many scenes. Some of the soundtrack used existing music for great effect (one of the things that sold me on the first episode was the frantic money cleaning scene towards the end of episode 1 set to "Out Of Time Man") and some was new.
It looks like the prequel will keep the same standard. But some of the well-chosen music isn't easy to identify. Hence the following question.
The new, and so far excellent, Breaking Bad prequel Better Call Saul has an unidentifiable piece of music over the end credits that sets some of the tone for the series. What is it? And was it made specially for the show or is it from an existing album?
Since the IMDB listing for the series doesn't yet include any soundtrack listing, I'm hoping to community can help.
