Cello music with a twist takes the stage tonight at the Oregon Shakespeare Festival's Green Show.

The free show featuring the Portland Cello Project is from 6:45 to 7:20 p.m. on the Pioneer Street bricks outside the OSF theaters.

OSF says the group plays everything from Beethoven to Britney Spears. On its Web site, Portland Cello Project refers to itself as a "somewhat intimidating 8-16 cello ensemble."
