the organization of the list of bandleaders by nationality in this article seems a bit arbitrary and perhaps not very useful would a different organization be better for example by era pre s s s etc or perhaps simply an alphabetical listing ignoring nationality or era it's also not clear if the nationality headings listed should refer to the nationality of the band or to the nationality of the bandleader for example toshiko akiyoshi led a north american big band for years years in los angeles and years in new york but she herself is a japanese citizen although she has resided in the us for over years
