Guns N' Roses' massive world tour in support of the simultaneously released Use Your Illusion I and Use Your Illusion II albums. The tour spanned 194 shows across 27 countries over two and a half years, making it one of the longest rock tours in history. Notable for the St. Louis riot on July 2, 1991, when Axl Rose left the stage after a confrontation with a fan at Riverport Amphitheatre. This was the last tour to feature original rhythm guitarist Izzy Stradlin.
