Understanding Destiny 2's interactive music (there might be some variations).

I didn't get Silence and Shadow (Action) in this playthrough, but IIRC it plays if the enemy team summons the primeval first.

New Arcadia Gambit soundtrack:

Valkirye (Action): youtu.be/qF4aA-3so4o
Silence and Shadow (Action): youtu.be/sKGRyarRddU
Silence and Shadow (High Action): youtu.be/LmEyRaI6FR4
