Soft rock icon Kenny G is set to serenade Smith Center audiences with his soprano saxophone playing a mix of R&B, pop, Latin and jazz. The Grammy Award-winning performer and composer has 11 platinum albums and eight others that have reached multi-platinum status, but he’s not just famous in the jazz world. He’s collaborated with everyone from Aretha Franklin, Frank Sinatra and Kayne West to Katy Perry. Add to that staring in Super Bowl commercials, and the HBO documentary “Listening to Kenny G.”
