The SOS Tour was the second concert tour and first arena tour by American singer-songwriter SZA, in support of her second studio album, SOS. It was announced on December 13, and commenced on February 21, 2023, in Columbus, Ohio. By its conclusion on May 2, 2024, in Melbourne, Australia, the SOS Tour comprised sixty-four shows. Lasting for about 90 minutes, every show had a set list of over 30 songs, most of which were from SOS. Some were taken from Ctrl, her debut studio album. Select shows had surprise guests who performed with SZA songs on which they had collaborated. Omar Apollo, Raye, and D4vd were the opening acts for each leg, respectively. A nautical visual motif persisted throughout the concerts, and theatrical and cinematic influences were apparent. This was intentional; with the tour, SZA aimed for catharsis: to "pop ass and cry and give theater". From Wikipedia
