Today (7th October), HaSeul of ARTMS held the first day of her solo concert Inner-Ego. One of her performances was a cover of “Blue Blood,” originally released in August. As she was on hiatus for health reasons, the song did not feature her vocals at all. Now it’s her time to put her own spin on it.
She’s known for applying an opera-inspired vocal technique to her parts across LOONA, ARTMS, and her own discographies. But HaSeul unleashed her inner rock star in her “Blue Blood” rendition. The live band for the event provided crisp electric guitar riffs and a lively drum rhythm as she built up to a magnificent crescendo.
Rock and classical collided in the bridge as violin strings were also brought into “Blue Blood.” HaSeul sounded like a human flute as she steadily ascended from an E♯5, to some gorgeous sustained G♯5s, climbing further to an A♯5, culminating in a glorious soprano high C (C6). Her guitarist’s shredding shortly after she sang the peak note is the cherry on top. Her pure head voice is truly a perfect match for such dramatic instrumentals.
On 2nd October, ARTMS officially released the demo version of “Blue Blood” due to fan demand. Although the demo version had stronger bass and a rawer feel, both versions stayed firmly within ARTMS’s signature electropop territory, incorporating brisk drum-and-bass loops. Who could’ve imagined it would be so amazing as a symphonic metal song?
Day two of Inner-Ego will take place on 8th November. Like day one, it will be held at the ECC Yeongsan Theater at Seoul’s Ewha Womans University.
