Ever wonder why some art is called modern art?

The Norton Museum of Art will take a look at art that crosses the line, and makes us question what’s art … and what’s not. Join the 5:30 p.m. pbpulse.com-sponsored tour, Crossing the Line, and see what the experts say.

Those who want to do more than just look can join the free art session, Sketchbook Thursday, from 6-8 p.m. in the European Galleries on the third floor of the Nessel wing. Live models will pose for you just like they do for the pros!

At 6:30 p.m., take a docent-led tour of modern sculpture.

David Shelley and Bluestone perform from 6:45-8:45 p.m. Offering an eclectic fusion of blues, rock and world rhythms, this band’s hard-driving grooves, soulful blues guitar and strong vocals are the heart of their sound.
