In 2006, Dave Grohl and his bandmates gathered over 80,000 people in Hyde Park. The band and the audience have mostly not recovered from it. As their latest album, "Echoes, Silence, Patience & Grace", continues to churn out hits, good news comes to hammer home the point and visually prove that the Foos are one of the essential bands in the rock world. A DVD that will excite more than one fan.
