I didn't want to say this because i don't want to get flamed, and i mean no disrespect, But the Drums (specifically the toms) sound to 'processed' and over sampled imo of course..dunno, it just lacks a bit of 'fatness' or 'feel'. Like Behemoths Apostasy where you 'feel' the toms every time he smacks 'em.
It sounds the same as the drum sound from JFAC and similar to Opeth's "deliverance" which I'm not too fond of. If you listen to "the formation of damnation" (the song) and JFAC's "reduced to mere filth" you can hear the similarity. Not sure the reason behind choosing that particular sound for drums 'cuz i know andy has done better (once again Just my opinion).
Despised Icon's latest had a slightly better tom sound, still sampled i know but doesn't lack as much body.
For a Band like Testament where the riffs and beats are really groovy and "head-bang-full" (not a real word) i would assume the "feel" aspect to be more dominant. (one again, no disrespect intended)
dunno, might just be a preference thing, I'm sure a lot of folks here will disagree with me.
