Longitude 2019 kicks off today with some last-minute changes to the line-up. Ski Mask The Slump God has been announced as the Friday night headliner, due to Swedish authorities deciding to hold the original headliner A$AP Rocky for an extra two weeks.

Longitude organiser's announced the news on Twitter today:

As we previously reported, A$AP Rocky was arrested in Stockholm earlier this week, after an incident involving the rapper and members of his entourage. He continues to be held  by authorities there on suspicion of gross assault.

In a video that appeared online, A$AP Rocky and his entourage appear to throw punches at two men - one of whom ends up on the ground during the altercation. The New York rapper also posted his own videos of the incident to Instagram in an effort to assert his innocence.

Ski Mask The Slump God is now set to close out the first night of the festival. The American rapper, who first came to global attention for his collaborations with the controversial deceased artist XXXTentacion, also plays Wireless Festival in London on Sunday. Ski Mask The Slump God released his debut album, Stokeley, last November, which peaked at No.6 in the Billboard 200 chart.

It was also announced yesterday that Pusha-T and rising Irish rapper Kojaque would be added to Friday's line-up, after Lil Uzi Vert cancelled his European tour.
