In this video Alex Mars, from XSSR Academy, takes a quick look at a training exercise called "Find 2 bands in a 7 frequencies equalizer".

The main goal of this exercise is to find 2 frequencies that are changed in the audio source and correct them. As Alex suggests, listen carefully and don't be afraid to play with the bands. You'll have to make a decision on how the audio sounds and how to make it better.

During the exercise, Alex uses a Coins' album called "Daft Science", available here.
