ROCK
What's in a name?
You can't beat tonight's indie rock lineup at T.T. the Bear's Place. Even the names are entertaining - Boston's own the Motion Sick (left) opens, with Springfield, Ill., bands Ha Ha Tonka and Someone Still Loves You Boris Yelstin to follow. The Motion Sick has had great success with its latest album, "The Truth Will Catch You, Just Wait . . ." earning Spin.com's "Band of the Month" honors, and you can boogie to the band's "30 Lives" on the latest "Dance Dance Revolution" video game. The tuneful Ha Ha Tonka and SSLYBY (possibly the worst abbreviation since NKOTB) are no slouches in the feet-moving department, either. 18+ 9 p.m. $10. T.T. the Bear's, 10 Brookline St., Cambridge. 617-562-8800. ttthebears.com
