On the final weekend of March 2018, Sebastian Ingrosso performed at Ultra Miami 2018 as Axwell Λ Ingrosso. The same festival also saw Ingrosso perform as Swedish House Mafia as the band reunited after a five-year hiatus on the festival’s 20th anniversary. On 29 June, Axwell Λ Ingrosso released their first single since their debut studio album, More Than You Know, featuring British singer RØMANS called “Dancing Alone”. A month later the duo performed at Tomorrowland 2018, in which they paid tribute to the late DJ Avicii as part of their set. In August 2018, Axwell Λ Ingrosso announced that they would be going on hiatus in order to focus on the Swedish House Mafia reunion and 2019 tour. For currently unknown reasons, Ingrosso cancelled a performance at Wynn Nightclub in Las Vegas.
