Ippu-Do was founded by Masami Tsuchiya in 1979 alongside Akira Mitake and Shoji Fujii. The band released five records, but Tsuchiya went on to release a slew of solo records as well as tour as a guitarist with Japan. With Steve Jansen replacing Shoji Fujii on drums, Night Mirage is a hulking play between towering new wave guitar, skewed synth pop, and avant-garde synth murk, with shades of calypso and a nod to Erik Satie.
The version I'm sharing is the 2006 Japanese re-issue, which includes Masami Tsuchiya's six-track experimental mini-album, Alone (1985). They're entirely instrumental, brooding, and very, very beautiful. Enjoy!
