High Voltage was a music festival, held twice in Victoria Park, London.
[2] The festival was not held in 2012 to avoid clashing with the London Olympics, and it did not return in 2013.
The set times for 2011 were announced on 18 July 2011.
[4] There was also an Evel Knievel exhibition; a beer festival with bands playing, including The Amber Herd who headlined on the Sunday; and the Ace Café area – featuring performances from The Crazy World of Arthur Brown (which was recorded and subsequently released on limited edition vinyl as The Crazy World of Arthur Brown Live at High Voltage), Aaron Keylock, and Allegra Shock.
[4] Electric Wizard couldn't make the festival in time, due to flight disruptions caused by events in Norway, so Rival Sons played a headline set in their place.
