Hard Rock Calling is an annual music festival that takes place in London's Hyde Park. With two stages, market stalls, and bars this definately has the festival vibe about it whilst still being a great family day out. The music this year is already got off to a great start with the iconic Pearl Jam and sir Paul McCartney already confirmed to headline this 3 day event. Music finishes around 1030pm every day leaving you loads of time to make your way home on public transport so theres no excuses to miss it, its going to be awseome.
