At the time, it was unclear why the UK government targeted the Spiral Tribe travelling sound system. Even after arresting many key members and launching one of Britain's biggest court cases against them. As Spiral Tribe's co-founder and visual artist (or as the Crown Prosecutor described him, 'the criminal ringleader' who'd helped 'mastermind' Britain's 'biggest ever illegal rave' at Castlemorton), Mark Angelo Harrison has a unique perspective to tell their inside story. He vividly charts their nomadic journey and the rapid escalation of their popularity - and notoriety. From small squat-scene parties in London to enormous warehouse raves and free festivals. From one little overloaded van to the mighty convoy of matt-black military vehicles that instigated the teknivals of Europe.
