Yeah Impending Doom plays in drop A.
my past 2 and current band play in drop A.
Black Dahlia Murder used to play in B standard, not sure if they still do.
I could have swore DI used 7 strings? which is automatically in B standard.
anyways i know they're in B, one of the few modern death/core bands that use a standard tuning versus a dropped tuning.

My current band used 7 strings, with the low string dropped to A.
so drop A 7 string?
idk; heavy as balls tho.
