What can you say about an artist whose career is aging like a fine wine? Kweli may be more popular now than he ever was with Mos Def in Black Star or Hi-Tek in Reflection Eternal. Certainly the commercial success is nice but his flow hasn't dipped a bit, and if anything, is more honed now on Gutter Rainbows than it was when he was spraying the streets with bar after bar of incredible lyricism. $20. 8:30 p.m. Amos' Southend, 1423 S.
