What was BLACKPINK’s 2016 debut single album called?

BLACKPINK’s 2016 debut single album was called Square One.

YG Entertainment released Square One on August 8, 2016. It contained two songs: “Whistle” and “Boombayah,” both of which introduced the South Korean quartet’s combination of hip-hop, pop and electronic production.

“Whistle” reached number one on South Korea’s Gaon Digital Chart, while “Boombayah” became an important early international track. The release established BLACKPINK as a major new K-pop act only weeks after its official debut.

Square One is not a full-length studio album. It is a single album, a format commonly used in K-pop for a short release containing a small number of tracks. The group followed it with Square Two in November 2016, then later released the EPs Square Up and Kill This Love. The word “Square” became a recurring part of BLACKPINK’s early release titles.
