(HIPHOP) Murs of the Living Legends is a prince of hiphop's underworld. He often collaborates with other princes of this realm, such as Slug (together they form Felt, who have released two solid CDs, A Tribute to Christina Ricci and A Tribute to Lisa Bonet) and also Aesop Rock. Murs's latest CD, Murray's Revenge, is by no means his best, but one of its tracks has the honor of possessing Murs's most bewildering title yet, "D.S.W.G. (Dark Skinned White Girls)." Race in America is becoming more and more complicated. (Chop Suey, 1325 E Madison St, 324-8000. 8 pm, $10 adv, all ages.)
