I knew '87 would be tough to pick. This list is further complicated by the fact that you've added some really great albums that are outside the genre and probably don't really belong on this particular list. It's impossible to not consider Appetite For Destruction one of the best even though it's not considered "alternative". Anyway, these polls are great as is this site. Thanks for carrying the torch for a genre that's often overlooked and forgotten.
All good, nor further comment
