Roll Deep - Shake A Leg

M.I.A. - Galang  Her style is unique to hip hop and its a clever reflection of growing up in two cultures: Tamil and British. 

Alpha Yaya Diallo - Freedom.  Another great example of combinging traditional West African (Guinea) music with modern electric instruments and styles.

One of the best examples of combining West African music (the roots of the Blues) with a modern Blues player is Taj Mahal's Kulanjan.  Go out and buy this album this weekend.  Do it. Do it.
