After finishing her performance as Harley Quinn in Joker: Folie à Deux, Lady Gaga felt she wasn't ready to leave the character behind. This experience led her to create Harlequin, an album inspired by the perspective of "Harley Quinn," or "Lee," as Gaga calls her. This album is both a farewell to the character and an artistic representation of Harley's chaos and energy.

Harlequin includes 13 songs that blend jazz, surf-punk, blues, and classical, offering a unique fusion that feels familiar yet innovative. While fans are eagerly awaiting her return to pop, Gaga continues to explore new musical directions, with Harlequin considered as a LG6.5: an intermediate album between Chromatica (LG6) and their upcoming major studio album (LG7).

The term LG6.5 is an unofficial reference used by fans and media to describe this album as a side or special project, among their sixth studio album (Chromatica, 2020) and the seventh (LG7). Gaga is known for experimenting with different musical styles and exploring artistic themes beyond traditional pop, which is why Harlequin It's in a unique category. It's not a mainstream pop album, but it's not a mere minor project either, as it delves deeper into the narrative and aesthetic of her Harley Quinn character.
