Lead them into war
Other than the Marley's, I don't listen to too much reggae. However, I came across Groundation and found that I really dig them. Known as "spiritual roots reggae," the group teamed up in Northern California back in '98. Typically they feature legendary roots performers on their albums and are known internationally, however still remaining in the "underground." "What Could Have Been" is the opening track to Upon the Bridge, their fifth LP. Truthfully, this is the only album I've heard by them and so I can't speak on whether it's good compared to the rest of their discography. All I can say is if you're at all into reggae, you should definitely check them out. If not, give them a try anyway--you might just discover that you like it!
