I know nothing about this music…
And this video can’t be embedded, but you really want to have a look.
Update: It helps tremendously to have readers all over the globe who can provide information. Duarte Amaral Netto wrote me: “Buraka is a Lisbon hard suburban zone (in fact it belongs to other city called Amadora, known for it’s emigrants) and can also mean a hole, Som Sistema is (easy) Sound System. Their name has irony and humor but it’s not sarcastic. They mix Angola’s Kuduro (Portugal’s ex colony) with electronic/dance music, and they’ve been clubbing all over Europe with great success. They are now touring in Australia. You can go to their label (they created it) and see other projects: http://www.enchufada.com/”. Thanks, Duarte!
