X Japan/YMMV

Crowning Music of Awesome: The 29 minute long (33 minutes when performed live) Art of Life, which went from gentle ballad to heavy rock to twelve-minute long piano solo and back again. The song, which was years in the making, tells a very clear, powerful story of someone pulling themselves through a BSOD.
- It's Yoshiki's autobiographical story to that point. The BSOD was, according to the Art of Life DVD insert, his physical and mental collapse from "neurocirculatory asthenia" in the early 1990s.
Epic Riff: "Kurenai," "Art of Life," "Blue Blood," "Silent Jealousy."
Epic Rocking: Art of Life. See above.
Epileptic Trees: Without You, I.V., and Jade are a trilogy/lament/memorial of hide.
Everyone Is Jesus in Purgatory: "Week End" (an allegory for suicide and the "end of the world" as the "end of a life"), Rose Of Pain (Elizabeth Bathory), the 1994 anime Rusty Nail PV (cue jokes about Yoshiki's Messianic Complex that persist today, never mind he doesn't have one).
Harsher in Hindsight was an Averted Trope in Week End's PV in regard to hide, but may have been played heartbreakingly straight in relation to Taiji.
True Art Is Angsty: Both onstage and offstage.
