Cat Anderson was one of the greatest high note trumpeters of all time.
This.
Geoff Winstead is a professional musician in Southern California who studied with Cat for 8 years and is one of less than 10 actual students that Cat took under his wing (paw?) and may be the only one who went through his entire "method" with him.
He consistently played musical passages in the extreme upper register every night of his professional career from 1935 to 1981, most of it with the Duke Ellington Orchestra.
