−77.82X−78.29 (spoken as "negative seventy-seven point eight two by negative seventy-eight point two nine") marks the second extended play and fourth overall release from the South Korean girl group Everglow. Issued on September 21, 2020, through Yuehua Entertainment, the EP is presented in two distinct editions, −77.82X and −78.29, containing four tracks with the lead single "La Di Da".

Title

The title −77.82X−78.29 alludes to coordinates pointing to Antarctica, which is visually represented on the album’s cover art. During the album’s showcase event, member E:U mentioned that each of their releases forms part of the broader "Everglow universe," suggesting a continuous storyline that enriches their artistic identity and narrative approach.

Background

On September 7, 2020, Yuehua Entertainment revealed plans for Everglow's second mini-album, −77.82X−78.29, scheduled for release on September 21.

Between September 8 and 10, concept photos were unveiled, followed by the track listing on September 11. The EP includes four songs: the title track "La Di Da", "Untouchable", "Gxxd Boy", and "No Good Reason". Notably, member E:U contributed to writing the lyrics of "La Di Da".

The teaser for the "La Di Da" music video premiered on September 16, with the full video released simultaneously with the album on September 21.

Composition

Yuehua Entertainment characterized −77.82X−78.29 as a demonstration of Everglow's "intense and commanding presence," showcasing a more daring sound compared to their earlier works.

The lead track "La Di Da" blends uptempo electropop with retro influences, delivering a lyrical caution directed at insincere detractors during a perplexing time.

Promotion

Everglow conducted a live showcase on the album’s release date, performing both "La Di Da" and "Untouchable".

Promotional activities for "La Di Da" commenced on September 24 with a performance on Mnet's M Countdown, followed by appearances on KBS' Music Bank, MBC's Show! Music Core, and SBS' Inkigayo.
