Jessica Childress Slow Down

[LukasL]

I think its the mix bus compressor. You can hear it pump a bit after each kick hit for example. It ducks while the kick hits and the relatively long release leads to the rest slowly being turned up, which is audible.

If its not the mix bus compressor, it could also be a drum bus comp. At least thats what I am hearing.

Cheers,
Lukas
