An appreciation thread for old rap/hip hop. I'll start it out

There are earlier artists, but I find this group embodies a certain kind of holistic approach in their rap, like bring up the gospel, respect it but say, hey I want to learn more...

All entries are welcomed, it's a moving target, so it doesn't really have a time period in mind.

Does shout bring change?
