Task: Question Answering
Input (English): Passage: The urban AC stations resemble soft AC rather than hot AC; they play predominantly R&B and soul music with little hip-hop. This is reflected in many of the urban AC radio stations' taglines, such as "Today's R&B and classic soul", "The best variety of R&B hits and oldies" and "(City/Region)'s R&B leader". Urban AC's core artists include Luther Vandross, Trey Songz, Patti LaBelle, Toni Braxton, Whitney Houston, Aretha Franklin, Frank Ocean, Craig David and Mariah Carey. Question: Along with Trey Songz, Patti LaBelle, Toni Braxton, Whitney Houston, Aretha Franklin, Frank Ocean, Craig David and Mariah Carey, who is a well-known urban AC artist?
Output (English): Luther Vandross
