>> Artomatic continues with a bevy of daily events. Tonight Ellyn Weiss leads a “Colorfield Intermix Tour of Artomatic“, showing visitors works influenced by the Colorfield painting tradition. Even if you’re not well versed in art movements, it’s a good chance to get an overview of this month-long art extravaganza. [2121 Crystal Drive, Arlington, Va., Free, 8:30 p.m.]

>> Trumpeter and composer Chris Botti brings his pop and jazz standards to the Warner Theater. If you’re tired of the same old rock and roll din, it might be worth the $49 price tag to relax with Botti, who’s performed with the likes of Sting, Jill Scott and Steven Tyler. [1299 Pennsylvania Ave. NW, $49.50, 8:00 p.m.]

>> Olsson’s Books celebrates Poetry month by inviting customers to read their own poetry, or just share their favorite poem by another author. Head to Old Town Alexandria for this prosaic free-for-all. [106 S. Union St., Alexandria, Free, 7:00 p.m.]

>> TV on the Radio plays a second sold-out show at 9:30 club tonight. For fans who didn’t snag tickets in advance, we spotted plenty of reasonably-priced tickets still available on Craigslist. [815 V St., NW, 7:30 doors]
