The Matrix, located under the Roxy club, launches a new music series tonight with hip-hopper Sage Francis. . . . Tonight also sees the return of the amped-up Henry Rollins, who brings his new spoken-word tour (which is sure to be laced with some political observations) to the Berklee Performance Center. . . . World music icons Ladysmith Black Mambazo are at Sanders Theatre tonight, while the homegrown Waltham rocks Bill's Bar. . . . Tomorrow, look for Super Furry Animals at the Somerville Theatre, plus a twin bill with folkies Loudon Wainwright III and Cheryl Wheeler at Sanders Theatre, and an '80s flashback with the Lyres and the Real Kids at the Middle East Upstairs, joined by the Coffin Lids.
