The first track released off the album, "These Empty Walls," cracked the Billboard Hot 100 and rose to No. 1 on the U.K. Rock Chart. The poet/activist, who continues System's tradition of churning out meaning-heavy lyrics and expects to release his sophomore effort in 2009, performs tonight at the 9:30 Club, 815 V St. N.W., Washington. Doors open at 7:30 p.m. $25. Call 202-265-0930 or go to 930.com.
