Singer Solbi on Thursday announced an unscheduled new release for Friday, saying she will unveil the music video for the new song at 9 p.m. on YouTube.

The new album “Hyperism: Blue -- Class” is a follow-up to the EP “Hyperism: Red” that was released last May. The agency said that the new album would mark the artist’s attempt to expand her musical horizons.

She will hold an exhibition related to “Hyperism: Red” in early April.

Solbi debuted in 2006 as a member of Typhoon with the single “So.” Although the group was popular upon its debut, it disbanded in 2010 as she pursued a solo career.

The K-pop act reunited earlier this year.
