i listen to alot of music with double kick drums, and unfortunatley the metal scene has a tendency to not have the most money for recording, but if im going to use an album as a reference album i'll use Becoming the Archetypes's Terminate Damnation, it seems to be well recorded. either that or Impending Doom's Serpent Servant, its probably the only album that the sound isn't colored in, has good high and good lows.
