Morbid Angel's first three along with the live album for sure. After that the lineup and attitude of the band basically changed so the rest of it doesn't count in my book (I enjoy F but it was just Trey having fun and living off the advice of motivational speakers, which shows).
Burzum made it work for three albums, and so did Darkthrone., Vader, Bolthower, Immolation, Black Sabbath, Summoning, Metallica. Three or four seems to be about the limit for a band whose style has so many riffs in a brief period and lives so fast, although Summoning and maybe Graveland strikes me as an exception in that regard since they don't tour and never got involved in criminal behavior.
Plus the shitty deals these guys were given for writing music that almost never turned into a living makes it hard to believe there's as much quality material as there is, especially given how volatile the labels were. They usually have to support themselves with other jobs, after all.
