I went to Burning Man like the last 3 years, except that we really got a treat: Oakey and Tiësto played there. You can read my Burning Man 2005 report for lots of pictures and details on the event.
But in a nutshell, it was payday for Trance Lovers, as Armin would say: Oakey and Tiësto's appearances were not really widely announced, which is good as it kept the attendance to Burning Man attendees, as opposed to people who might have attended Burning Man mostly unprepared and as tourists, just to see those two start DJs.
Anyway, Oakey did a very enjoyable set, especially for his fans like me who recognized all the tracks he played from his 1996 debut with Dragonfly, a Voyage into Trance. All I can say is thank you so much Oakey.

The pictures and videos are here
(note that most are dark and coarse grained because you mostly can't take flash pictures at Burning Man due to the dust that is flying everywhere in the air. Also, Oakey was smiling and having a great time, I just got unlucky on most of the pictures I took)
