At 22 years old, Theo Croker has already distinguished himself as a vital force in the jazz community. As the grandson of jazz trumpet legend Doc Cheatham, part of Louis Armstrong Jazz Oral History Project, Croker's legacy is profoundly felt when he plays. Legendary trumpeter Donald Byrd, said about Croker, "There are good, great and nice musical players, but then there are phenomenal instrumentalist such as Theo. I would place Theo in a class of musicians who will redirect the flow, change and alter the current of today’s New Jazz ... Theo is one of today’s titans."
