RYTHEM, a two-person duo known for their harmonies, makes their debut as their differently colored voices blend to produce a crackling, ultrasonic effect. They recognize each other as more than just friends, and they boast a versatile talent that handles not only writing and composing but also harmony arrangement and even artwork with exquisite finesse. From the everyday, contemporary perspective of living in the modern world, they tackle the big theme of “What is happiness?” and send their message from multiple viewpoints. After ten years of recharging, they returned in 2021 to revolutionize the music scene—the “Rhythm that Delivers Happiness” delivering joy—and their performance on Billboard Live’s stage is sure to be worth watching.
