Passacaglia

The track takes Handel's passacaglia and drags it into hardcore techno territory courtesy of SynthWulf. It made a dual debut, appearing at the same time in Fiesta 2 and Infinity. Pump It Up Rise carries a version with remastered audio. As a side note, the October 22 XX update added an avatar named "Count Lawrence," priced at 3,500 PP.

The most distinctive feature of the harder charts is a forced Earth Worm (EW) option, which makes the notes appear to teleport up and down the field. This calls for caution: if you play a level 17 or higher chart (up through XX) with your own Earth Worm modifier on, the two effects stack and the chart becomes essentially unreadable. From PHOENIX onward, some of these EW segments were removed or toned down across several charts.

By PHOENIX data, Single offers S4, S8, S12, S17, and S19, while Double covers D14, D18, D22, D23, and D25, plus a Short Cut with S17 and D18. The S17 gives few breathers and, up through Prime 2, was a notorious overrated S16, ranking among the hardest of its level alongside Chimera and Extravaganza. The D25, newly created in the PHOENIX 2.12.0 update, was poorly received for its chaotic alternating-foot placements; Jboy himself criticized it harshly, and many would rather have the old Infinity D25 brought back.
