Though Buraka Som Sistema is infrequently mentioned on XLR8R as of late, the Portuguese outfit's label has a bit of news for us: Starting today, Enchufada is releasing a bi-monthly series of free singles. Under the banner of Upper Cuts, each free track will appear on the second and fourth Wednesday of every month, with a physical release of the entire collection arriving after a total of six months. Enchufada promises exclusive tracks from such up-and-coming artists as 5kinandbone5, :PAPERCUTZ, Klipar, and other label mates. The first Upper Cuts single is available now, courtesy of Buraka Som Sistema co-founder Branko, who collaborated with Njena Reddd Foxxx (of "Ima Read" fame) on a slice of fiery "ghetto dance music" called "(One More) Silly Bitch." You can stream and download the track below, and be sure to keep your eyes peeled for the rest of Upper Cuts to appear in the weeks to come.
