Richard Reagh on The Latin Kings and the roots of Swedish-language hip-hop: http://www.reagh.net/downloads/latin-kings-det-e-slut-det-ar-dej-jag-vill-ha/
Like Richard says, these guys are the forefathers of the scene, still considered by many to be the best. I think the Swedish hip-hop scene is still fairly young and exciting, so there's tons of potential for growth, especially when the artists move beyond trying to copy US stuff.
