ハローイチイチゼロサン。Hitomi (Trackmaker)、yukako (VJ)によるユニット。
2019年よりRegular Setによるライブに加え、静謐な美しさを求めたAmbient Setを開始。ライブハウスでの演奏にとどまらない活動を展開し、好評を博している。

VJとしては即興的なエフェクト操作によってリアルタイムに映像を生成するスタイルを持ち、自身のライブでの演奏にとどまらずmouse on the keysをはじめとして数多くのミュージシャンの映像演出を手がけ、またライブハウスの映像制御システムの構築も行う。

An electronic music duo composed of Hitomi (Trackmaker) and yukako (VJ). Their organic digital sound and lyrical melodies are accompanied with visuals that depict subconscious imagery, creating an extraordinary space. Based in Tokyo, the duo is active both domestically and internationally. In July 2019, the duo commenced their Hello1103 Ambient Set which includes a collection of tranquil tracks. As with their conventional performances, this new setup is being received positively at various venues.

Other than VJ work for their own performances, the band has offered visual effects for many musicians including mouse on the keys. The band also offers consultation for visual systems at live venues.
