Yes the night before I saw this exact show in Los Angeles at the lovely Royce Hall, UCLA, lucky for me I was in the perfect spot to see the show, six row dead center.
Youssef was a very pleasant surprise, no one I knew was expecting it, he was very heady and energetic. Then Jon and the band came out and blew us all away. Such a delicate set of music from something mostly electronic based. Jon set a new bar for restraint and refinement with lots of energy in a live concert environment. I kept thinking in the movie Blade Runner if their had been an opium den, then Jon and his band would have been the house band for it.
Speaking of Steve Roach, Steve flew in from Tucson for the day just to see the show. He and Jeff Fayman sat next to me. The only other ambient guy I saw at the show was Tom Heasley. After the show we got to speak to Jon very briefly, he mentioned he was flying into Vancouver that morning, they had a 4:30 AM flight, and that he had not slept in two days! After that we decided to leave him alone so he could maybe get a bit of sleep before catching his flight. A great show, the highlight of the year so far.
