Originally released in Japan in 2015 on DJ Emma’s Nitelist Music as part of its Acid EP series, only a small handful of copies of this 12” made it to Europe. JD Twitch was lucky to score a copy and both tracks became firm favourites in his sets and much asked about. Twitch felt this music deserved a wider audience so was kindly granted permission to reissue it on Optimo Trax. Yes another double A side release, A1, Hiroshi Watanabe’s - Infinity Sign is a hypno ecstatic acid piano-tingling monolith. A2, Kuniyuki’s Acid Air is a slow building organic percussive acid freak out that WILL cause a freak out on the floor. It is hard to do anything with a 303 that is interesting these days but both the tracks on this 12" are 100% club classic.
