to be honest, some albums are underappreciated, under the radar or under rated because no one knows it's out. the artist may have good music but terrible business sense. anyway, i'm trying to think of albums that suit this criteria.
i guess i'd say any project born album
same goes for any doomsday productions albums
but i guess you want an actual album so i'll say this
loced out "product of da game" out of pittsburg
land of da lost "gone fishin'" not sure where they're from, i assume somewhere in east coco. also i think one of the rappers wrote for murder dog.
