I recently came across this video by chance and was very impressed by Rich Brown. Firstly, there is his confident way of accompanying - but look at his solo. What he plays is not revolutionary but very effective... he doesn't try to outdo the rhythmic complexity of Ledbetter's solo but rather approaches it very calmly and almost searchingly - and what a beautiful bass sound he has! The spirituality that he radiates has something almost Coltranesque about it. I then watched some of his YT videos - really very impressive, also as a bass teacher.
