Annual festival in Arena Lillomarka in Groruddalen.
The free festival has no age limit, no alcohol and plenty of room. The arena by the forest has almost unlimited space, and the number of daily visitors gets up to 20,000 people.
Rock music is the festival's main ingredient, but hip-hop also plays an important part. Bands like Turbonegro and BigBang have headlined previous Granittrock festivals.
