There doesn't seem to be many artists like Roberta Flack in pop music anymore. This classically trained musician is able to create colorful sounds that are silky smooth and filled with great passion which appears to be deceptively effortless. She may not possess a big voice but Roberta Flack certainly knows how to use what she has for maximum effect.
Although her output has slowed down, Roberta Flack has continued to tour and make new music. Her last album, "Let It Be Roberta: Roberta Flack Sings The Beatles" was released in 2012. It was slightly challenging to narrow down but here are my two favorite songs by Roberta Flack:
"Feel Like Makin' Love" - Roberta Flack (1974)
"The Closer I Get To You" - Roberta Flack Featuring Donny Hathaway (1978)
As a bonus, here are the Fugees with Roberta Flack performing their hit song live at the 1996 MTV Music Awards:
