Sistars is a Polish hip-hop/R'n'B band founded in 2001 by Natu and Pinnawela (the line-up was completed at the end of 2002, when Przemyslaw Maciolek joined). Their style also incorporates elements of funk and soul. Sistars were put on the map through a guest performance in a song called Zeszyt rymow (The Rhyme Sketchbook) by Polish rapper Tede. On 15th March, 2003 came their debut album, Sila siostr (Sister Power) with guest appearances by O.S.T.R., Tede, Ania Szarmach and others. The album was promoted by the single "Spadaj" ("Sod off") along with a video clip.
