Charlie Wilson's Tiny Desk unexpectedly ran the gamut of emotions. His musical journey boasts some of the highest highs and fanfare for over 50 years. So much so, it's easy to forget what he's endured. His testimonial during a praise break reminded us that he's climbed through valleys about as deep as they get. "I went from rags to riches, riches to rags, then rags to the curb, the curb to homeless," he said. "Because I was an alcoholic and a crack cocaine addict! But I'm 28 years clean and sober!"

Flanked by a host of musicians, Wilson expressed the depth and breadth of his life and career, telling a tale of two Charlies. The Oklahoma native's success with The Gap Band, formed with his brothers Robert and Ronnie, began in the 1970s and stretched throughout the '80s. The group's many hits are classified as old-school funk and R&B, but it's the resurrection and connection with young hip-hop stars that make Charlie's story so compelling to me.

Snoop Dogg was the first to hop on board, coining him "Uncle Charlie" and featuring him on his second LP, Tha Doggfather in 1996. They've been frequent collaborators since, eventually landing the smash, "Beautiful," a few years later. From Kanye West to Tyler, The Creator, Nas, and more recently Don Toliver and Devin Morrison, Wilson has been hip-hop's secret sauce for decades. When I asked Uncle Charlie to explain the reason why he's such a draw in hip-hop, he said so much by simply stating: "I can sang!"
