Harlequin' features polished takes of the songs from the movie plus two original songs, and the album will drop on vinyl and CD on Oct. 11

If Joaquin Phoenix’s portrayal of Arthur Fleck for “Joker” (2019) required him to tap into his own madness, “World On A String” captures Lady Gaga’s descent into madness alongside him. Sure enough, she infuses much of “Harlequin” with the pathos of her psychologically unstable Quinzel.

Harlequin” is a companion album for the film, in which Gaga stars as Lee, also better known as the unhinged villain Harley Quinn.
