Nightride FM was a radio station in Grand Theft Auto V, and its host was supposed to be DJ Kavinsky. Announced in early 2012 and confirmed by Kavinsky himself, the station has since then completely vanished, and does not seem to be included in GTA V.
DJ: Kavinsky, real name Vincent Belorgey, a former actor 2001-2007 and musician since 2006. He has toured alongside Justice, Daft Punk and SebastiAn. He is most famous for the song "Nightcall", which was featured in the film Drive (also in 2011, his music was also featured in the film The Lincoln Lawyer). SebastiAn's remix of his song "Testarossa Autodrive" appears on GTA IV's Electro-Choc.
