I just read a post that reminded me of GTA3 and went to go look up the Rise FM mix, since it was always one of my favorite stations from the game. From looking through comments, I learned that apparently people have been looking for Andre "The Accelerator", the DJ of Rise FM, for 20 years, and 2 weeks ago this guy confirmed it on youtube/twitter
