Yes, I know it's a rather strange name for a band (they're German), but you won't worry about that anymore from the moment you hear their music. The genre of jazz is rather 'new' (in terms of jazz, that is let's say 15-20 years), but it's gaining more and more fans every day. Let's hope you guys like it as well!
The genre I was talking about is called 'dark jazz' and well, that's about it. It's the perfect name for that genre because it is in fact dark jazz.
I'm telling you, and you can take my word for it, this is the perfect background music; I dare you to find anything better. Would also be good for use in movies. Let's check it out!
