What if Phillip Glass was boss music?

I previously posted a video of free jazz linearly tacked on a gameplay capture from Elden Ring, imagining the work of the group AMM as an alternative to the regularly-flavoured boss music for that type of game.

Last week I was deeply submerged in Phillip Glass' Glassworks, especially "Rubric", and I once again ended up at the thought: "this could be great, dynamically-implemented boss music".
The energy, the movement, the strict composition and changes in timbre. There was something in the instrumentation that made me think of ascension and flight.

Whilst the video shown here is edited-down sections of the "Rubric", linearly tacked on a gameplay capture from Shadow of the Colossus (for which I found a video of the bossfight with the music muted), I initially tried to implement this as a dynamic system using my ReaperToWwise tool, editing the piece down to small looped-segments, meticulous adding warp markers to make sure they flowed well segment-to-segment, and that they could be exited at relevant custom marker positions, but the transitions between state changes were not all that possible to pull off with just the stereo file - and I obviously don't have the stems at hand. It was worth a shot anyway.

I still think it was worth trying it out solely in Reaper, to see how it could flow by slightly editing it to match perceived state changes, which is what I ended up doing.

So yes, I'm sure Phillip Glass could write great boss music.
