The Glastonbury Symposium is one of Britain's longest-running and most acclaimed 'alternative' conferences and it is back this year with a line-up of excellent speakers, and a live streaming option.

Symposium speakers are all original thinkers with lots of cutting-edge ideas and discoveries to share, from exploring new and insightful views on current events, global consciousness, conspiracies and the fight for free expression, to classic areas of UFOs, near-death experiences, earth mysteries and, of course, crop circles.
