Mick Jagger on Brian Jones’ Moroccan tapes:
“I remember Brian playing his Moroccan tapes in the ’60s. We had this engineer we were working with, George Chkiantz, and George was one of the first people to be heavily into phasing, which was like the scratching of the middle ’60s. So Brian took all of the Joujouka tapes and put them through phasing, which was really quite before its time. I always felt the Stones were quite adventurous that way.”
