Probably one of the most respected Duos in the whole Hip-Hop community.
Guru which stands for Gifted Unlimited Rhymes Universal and DJ Premier which stands for DJ Premier
Here are some of my favorite songs.
Guru sadly died 2010
He had a side project called "Jazzmatazz" which I highly recommend you check out.
Dj Premier is probably the most influencential Producer.
I dont want to sound like my father....but music was better in the old days
