this video sequence was recorded on a trip to pittsburgh to see the james turrell exhibit at the mattress factory. it was one of the most rewarding exhibits i have seen in many years. it was made even more exciting in that i had the opportunity to speak with james turrell at a barnett newman symposium in philadelphia a couple months prior. -- title: COLOUR AND CONCRETE -- artist: michael ammerman -- year: 2002 -- size: 16 mb -- music: antenne . here to go (metamatics remix)
