Artists Of Different Genres That Would Make A Classic LP

Name some artists of two completely different genres that would (hypothetically) make a classic album together.
Artists can be past or present, dead or alive.






Bone Thugs/Earth Wind and Fire = Harmony + Precision + Real Life
Andre 3000/Prince = Im gettin some tonight
Dr. Dre/Quincy Jones = Mixing + arranging + production

I wanna say Krayzie Bone and Nate Dogg but they might be in the same genre.
*shrugs* fuck it.
