I want to know the answer to the following question:
Of what genre was the musician Keith Sweat?
All the background I'm provided with is that "In the 1980s, lush jazz-R&B fusion (George Benson, Patti Austin, Al Jarreau) and stylish crossover R&B (Anita Baker and Luther Vandross, New Edition and Keith Sweat) were equally successful within the mainstream.". Is that enough to answer the question?
