Today marks the 25th anniversary of the official beginning of Guns N' Roses' Use Your Illusion Tour. I say official because they played at Rock in Rio II and some warm up shows. The tour ran eight legs and was one of the longest in history as it went 26 months eventually concluding on July 17, 1993 in Buenos Aires, Argentina. The tour featured many big and infamous GNR moments including two riots on July 2, 1991 and August 8, 1992 but it also featured the band performing at the Freddie Mercury Tribute Concert at Wembley Stadium on April 20, 1992. The tour was the first for keyboardist Dizzy Reed as an official member and drummer Matt Sorum. It also featured a lineup change with rhythm guitarist Izzy Stradlin who quit the band on November 7, 1991 and was replaced by Gilby Clarke though Stradlin returned for five shows to fill in for an injured Clarke. Until this year, the tour would be the final one for Slash and Duff McKagan who eventually left the band in 1996 and 1997 respectively.
