Swedish House Mafia have teased new single "Frankenstein" featuring A$AP Rocky while he's still detained in Sweden.
A$AP Rocky was arrested in Stockholm on suspicion of assault earlier this month, and has had to cancel many of his festival appearances after being detained.
Following the news of his arrest, Swedish House Mafia shared an image of an unreleased song titled "Frankenstein", which features A$AP Rocky.
Swedish House Mafia haven't released new music since 2012's Until Now record.
Last week A$AP Mob launched a petition for A$AP Rocky to be released, which, at the time of writing this article, has gained over 590,000 signatures.
In support of A$AP Rocky, Tyler, The Creator, ScHoolboy Q, and Lil Yachty revealed they'll never visit Sweden again.
