Rolling Quartz Members: Five Names and the Instruments They Play

Rolling Quartz is a five-member Korean rock band: Jayoung sings, Iree and Hyunjung play guitar, Arem plays bass, and Yeongeun plays drums. For a first introduction, follow those instruments in the official “Blaze” video, then try “Victory.” You can learn the names through what each person does on stage.

Five names, with a useful stage reference

The current Leo Presents artist page lists this lineup. In their Rolling Stone Korea interview, the members also introduce their own instruments. These are musical roles; they do not tell you who wrote every note or how a particular recording was produced.

Start with the voice, then widen your attention

It is easy to stay with the singer when learning a band. On your first play, use Jayoung’s vocal as the thread through the song. On a replay, choose one instrument to follow. That gives you a manageable task instead of five names competing for your attention.

With two guitarists, avoid guessing a member’s identity from which side of a video she appears on. Camera cuts and stage arrangements can change. Use the credited name and a clear photograph together, then notice how the two guitars fit around the vocal.

“Blaze” is the beginning; “Victory” is another route

The artist channel identifies “Blaze” as the official debut single. Start there if your question is where the band’s recorded introduction begins. “Victory” provides a second complete official music video once you have a first reference point.

Try comparing one section from each song: an opening, a chorus, or the passage before the final return. Ask which part made you want to keep listening. You do not need a technical genre vocabulary to notice a voice, a repeated rhythm, or a guitar phrase you want to hear again.

These are two entry points, rather than a claim about the band’s newest release or its best song. The videos below identify their own titles; the photographs show separate 2026 performances.

Give the rhythm section a turn

On another replay, focus on Arem and Yeongeun. Bass and drums are different roles, even when both help you follow the pulse. Try listening for the lower-pitched instrumental movement, then for the drum pattern around the vocal. Treat that as an attention exercise, not a test you need to pass.
