Overcomming Fear Commentary Sound Very Low?

[BadServo]

I've bought all the short releases and this is the only occasion I've noticed a problem.  Essentially the Riffing portion of the audio is unusually low.  As if it's not "ducking" enough when the fellas are talking.  Has anyone else noticed this... or is it just me?

For reference, I'm watching the MPEG-2 version.
