Listen to this demo through a program like winamp that has a decent equalizer. Activate the equalizer then lower 60, 170 and 16k frequencies as much as possible so they are muted and slightly raise 310 and 600 frequencies. This helps to remove a lot of the muddiness the bass frequencies give the file and annoying squirly sound in the higher frequencies. It won't be perfect, but you can hear a lot more going on, I could even hear a few guitar solos and it definately made it a much more enjoyable listen.
