With 212 artists and more than 125 live performances, the Main Street Fort Worth Arts Festival offers a variety of art, food and music. The festival started Thursday and will run all weekend. Admission is free and with music acts going on stage as early as 11 a.m., there’s plenty to see all day. The festival also brings a number of big names to Cowtown for free shows. Here are a few can’t-miss shows.Otis Day & The Knights

Known for the “Otis, my man!” shoutout during the frat party scene in “Animal House,” Otis Day & The Knights have spent the last 30 years making people “Shout.” They hit the Sundance Square Stage on Friday at 10 p.m.

Patty Griffin

Boston-based folk songwriter Patty Griffin has made a career out her literate, thoughtful lyricism and subtle Americana arrangement. She brings her considerable talents to the Sundance Square Stage on Saturday at 8 p.m.

Ingram Hill

Ingram Hill calls its sound “pop rock with a Southern twist.” With influences from Lynyrd Skynyrd to Billy Joel, Ingram Hill has forged a totally new sound. Ingram Hill will play the American Airlines Stage on Saturday at 10 p.m.

OK Go

If nothing else, OK Go is the only band to have a line-by-line response to the Rolling Stones’ “Sympathy for the Devil.” Ok Go will bring back the good ol’ fashioned rock ‘n’ roll to the American Airlines Stage on Friday at 10 p.m.
