ハイスイノナサ (haisuinonasa) is a Japanese math/post-rock band formed in 2004. Read Full Bio ↴ハイスイノナサ (haisuinonasa) is a Japanese math/post-rock band formed in 2004.

The band’s original lineup consisted of guitarist Yoshimasa Terui, bassist Atsumasa Terui, keyboardist Tomoyuki Tamura, and drummer Keisuke Nakamura before being joined by vocalist and keyboardist Ai Kamano in 2005. Tamura left the band in 2012 and was eventually replaced by Kazuki Moriya in 2015. In mid-2016, ハイスイノナサ announced Kamano’s withdrawal from the group, and in 2017 percussionist Kaori Satoh, keyboardist Yuriko Sakurai, and vocalists Orika Okachi & Shiori Matsushima were added to form their current eight-member lineup.

ハイスイノナサ’s music is simply unclassifiable – there are hints of post-rock, minimal music, prog-rock, electronica, and all sorts of styles and influences. They weave a dreamy, narrative tapestry of piano-driven breakbeat (as some may call it) by filtering through pop music with innovative uses of tones and timbres. One thing is for certain, if you are into polyrhythms and ostinatos, you’re in for a treat.
