I already know about early Morbid Angel, Cannibal Corpse, and Obituary.

Looking for more stuff to play along with without having to retune my guitars.

Anymore gems out there (esp. old school) that I've overlooked?

Thanks.

I used to love playing along to Gomorrah's "Umbilical Divorce" demo, which is in E standard. I believe they stayed that way on their albums too.

Nocturnus's The Key! Andromeda Strain was a blast to play

Atheist's first three albums also are in E standard, and really tough to play

Oh yeah! Almost forgot about those!

Need to learn "Lake of Fire" anyway.

Yeah! That song is great fun too!

Another obvious one that i remembered only now: Pestilence's Testimony of the Ancients it's all in E standard, we used to play Land of Tears as cover in band i was into

Demise of Time is another song with some tricky rythms that i like to play, E standard too

Oh yeah, that Pestilence is a great one. So many good tracks. "Twisted Truth" was my jam.

I also remembered that the first two Sadist albums are in Eb: i really like their music but they are a bit odd, with some complex riffs and very frontal keyboards.
Tribe was a really fun song to play and at 2.16 it has a crazy bridge wich needs lots of right-left hand coordination

I thought you said Sadus at first and I thought "already all over that".

I don't know Sadist really though of course I have heard the name. I will check it out.
