Lisbon's Buraka Som Sistema have been one of the breakout acts of the year with their debut album 'Black Diamond'. Their now infamous live show - hailed by New York Times as the "best of Coachella Festival 2009" and received a glowing 5* live review from the Guardian, has been sending crowds mental around the world and literally sold out every single date in Europe & USA.

So, what do they do next? They write another great single.

'Restless' serves to remind us how inventive and inspiring they are. It's a fantastic single which producer J-Wow ichatted to Radio 1's Annie Mac direct from the studio. The next day she played it out and raved about it on dance music's most influential radio show.
