A rock band will have to face the music after blocking a Los Angeles freeway and performing atop its trailer. California Highway Patrol spokesman Rick Quintero said a big box van decorated with Imperial Stars' logo stopped on the southbound U.S. 101 near Sunset Boulevard at about 10:30 a.m. Tuesday, blocking four of the five lanes.

The driver took the keys and fled in another car, then three musicians climbed on top of the van and began to perform.

Quintero said they were arrested and the truck was finally towed away around noon after causing a mile-long traffic jam.

Quintero said the musicians could face charges of obstructing traffic.

The group, whose credits include "Traffic Jam 101," said on its website it is dedicated to helping homeless children.
