Although the members of the band have never explained the decision to retire from touring, fans believe one of the reasons behind this was at the expense of vocalist/bassist Tom Araya's desire of no longer wanting to tour and spend more time with his family. The tour was announced on January 22, 2018, through a video featuring a montage of press clippings, early posters and press photos spanning Slayer's entire career. The tour, consisting of 147 shows worldwide, served as a conclusion of the band's three-and-a-half-decade-long career. The Final World Tour (also referred to as The Farewell Tour) was the final concert tour by American thrash metal band Slayer, which began on May 10, 2018, and ended on November 30, 2019. 2018–19 concert tour by Slayer Slayer Final World Tour Tour by Slayer
