back up track

[Lyra]

Как перевести playing to a back up track ? Для запасного трека? Или как?

Контекст:
Bob plays drums on our record and so at first it was just Bob and I playing to a back up track and then we were like “Oh wait, we should probably have an actual person play drums”

Спасибо!

Bob and I playing TO a back up track - мы играли, а фоном шла запись барабанов
уж как-нибудь перефразируйте
