I like to listen to ambient music when I want to be relaxed and focused at the same time. Brian Eno´s early ambient works, work great for me. The album "Appollo" is a personal favorite by Brian Eno. The double album "Selected ambient works vol II," by Richard D James of Aphex Twin, is another favorite that scores high in my book. Patrick ´O Hearn is another great ambient composer that I like, the soundtrack from "Crying Freeman," by Patrick ´O Hearn is one of the best albums I have heard. And last but definetaly not the least I have to mention Peter Gabriel´s soundtrack from the film "Birdy."
