Members of a rock band that performed on a Los Angeles freeway and blocked traffic for hours have pleaded not guilty to various charges.
Christopher Wright, David Hale and Keith Yackey entered pleas Wednesday to conspiracy, creating a public nuisance and other crimes. They face up to three years in prison if convicted.

The judge doubled their bail to $20,000 each. Prosecutors say the members of the Orange County band Imperial Stars climbed atop a truck that deliberately stopped on U.S. 101 near Sunset Boulevard in October. The trio performed a song called "Traffic Jam 101."

Outside court, band members told City News Service that the stunt raised awareness for their charitable goal of helping homeless children.
