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 1900 1900 1909 1910s 1920s 1930s 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 30 years 10 years in Los Angeles and 20 years in New York but she herself is a Japanese citizen although she has resided in the US for over 50 years
