Finally got round to really listening to the excellent Blood Machines soundtrack and discovered that the ending of Grand Finale has something familar layered gently in there.
The reprisal comes in at around 5 minutes. Really nice touch from Carpenter Brut! The whole thing is fire, but I especially loved this track, the title theme and Soul's Wreck.
Good to know, thanks! I really need to spend more time (and money!) on Bandcamp, it's an awesome way to support musicians.
