A Site De La Rue

Though many PIU players know it as a guest track, "A Site De La Rue" is first and foremost an icon of the EZ2AC series, where it debuted in EZ2AC: ENDLESS CIRCULATION (2013) in a clear boss song role. It is KIEN's second piece released under the STREME REVERIE name. The track is a British-style hardcore number driven by a fast 186 BPM and a melody that suits rhythm games perfectly. Its genre was first labeled "Speed Core," but since real speedcore typically sits above 300 BPM, it was eventually renamed "Subway Techno." Its signature element is the "Ho!" scratch sample, which according to Flow.D appears exactly 204 times, to the point that fans nickname other songs reusing the effect "○-laru."

The BGA was handled by Flow.D and conveys a strong sense of speed in cool blue tones, widely praised for matching the music. Notably, its backdrop is not CG at all but edited footage of the Shinbundang subway line's tracks, a detail that helps explain the genre's shift to "Subway Techno." The title itself sparked debate, since it can be read either as a French phrase or as a proper noun (De La Rue, a lunar feature); the composer and the dev team settled the matter by reading it the English way, and the Pump It Up version keeps it as "A Site De La Rue."

The Pump It Up port arrived via a cross-franchise rhythm-game collaboration during the PHOENIX era. The song offers a spread of levels in both Single and Double: in Single it appears as S9, S11, S16, and S19, while in Double it covers D14, D19, and D24, ranging from mid-level fare up to demanding high-end charts. Its standing in the rhythm-game community, together with the punch of its "Ho!" sample, made it a much-celebrated addition to the PIU library.
