as i go between the meshuggah records, some are bright, some are more mid rangey. and the brain gets used to each condition after a few minutes. when i switch to another record, THAT record feels foreign and strange, and the one i was listening to felt just right, where as before listening, this would have been the strange one relative to the prior listening. thus its hard to be objective amongst nromalization of subjectivity. because of this, one needs to be careful during composition.
