I remixed all the prerecorded audio in this song.

The snare was pretty consistent but lacked any presence. I routed some of the drums to a parallel compressor track that had a really high ratio to add a tail to the snare and other elements.

Along with some distortion on the drums, I automated an EQ to take out some frequencies that were clashing with the backing vocals in the section with all the chanting.

The synth bass does a lot of sweeps into the higher frequencies which interferes with the vocals and drums, so I compressed it pretty hard with a multiband. There is a sub bass that plays along with the synth, so I used a low cut to remove any potential phase issues.

Down below are the settings for the snare (left) and the bass synth (right).
