I just discovered Al Jarreau a Jazz Vocalist artist that was born In Milwaukee Wisconsin .
March 12, 1940, -February 12, 2017, he died from Respiratory insufficiency in Los Angeles, CA.
I always forget that the human body can be instruments and people that do Scat -Singing and Vocal percussionist are simply amazing .
