The band is called Letecki Pekinezeri (Flying Pekingese). They're a Macedonian jazz band. I've never seen them live but I will when I get the chance.
I think my first real encounter with jazz music was at a small jazz festival near my town a few years ago. I was there for other reasons and my mom and I decided to stay and listen. I'm so glad we did. I loved it. I knew about jazz music before, but I think this was the first time I really listened and liked it so much.
Some time after that someone posted a link to the video above on Twitter. I listened to it and loved it. Ever since I have a habit of listening to this every once in a while.
Now click play, sit back, relax and enjoy. You can thank me later. =)
