I wish there was an Original mix... All we have left is a tiny snippet, and it sounds sick. Maybe as my birthday gift, Mr. Christopherson...? Please? (Don't harass him though!!!)

There is also a Stealth-Only Heist version of this track, which will use Domestic Scars normally, but switch to I'm My Own Master Now (Instrumental, mimics Blade Wolf DLC Alert behaviour) when the alarm is triggered, but implementation is wonky unless I can figure out a way to get the game to ignore most of the stealth events besides the initial one and the Point of No Return timer. If you have issues getting the stealth-only track to play, you may need the Music Volume Mixer mod which fixes some bugs related to custom stealth-only tracks, and will need to hover over the track in preplanning to activate the music preview right before starting the heist in order to load it properly. This is less a problem with my mod and more just the stealth-only music module itself.
