It’s been years since I last wrote about a Heize track. She falls in a murky territory that’s not always covered on The Bias List: not an idol herself but often poppy enough to exist within that framework. Today, she’s out with her second full-length album, led by the funky Undo (없었던 일로). The genre proves to be a great match for her skills, offering a slightly more mature take on what many idol groups are doing these days.
Undo opens with rugged synth, promising a dynamic track to come. That bombast never quite reappears, replaced by a groovy, city pop inspired instrumental. It’s nothing we haven’t heard a hundred times before, but the beat is consistently satisfying. It’s upbeat enough to dance to, but chill enough to play in more subdued circles. This balance works for Heize, who imbues the song with her trademark vocal tone. Like the production itself, her performance is aloof and naturally cool.
Melodically, Undo is solid but hesitant. It never goes for the jugular the way a great pop song might, but makes room for a few dramatic turns that keep the track from becoming forgettable coffeehouse fare. The verses and pre-chorus are its strongest assets, offering contrasting energies that play well back-to-back. When stacked against these segments, the chorus feels a bit underwhelming – conceding to the groove rather than elevating it. But overall, this is my favorite Heize single in quite some time.
