The ‘Mound City’ in question is St. Louis, jazz kazooist Red McKenzie’s hometown. Between 1923 and 1936 he led a musical moveable feast called the Mound City Blue Blowers that often contained some of the best names in jazz, including:

• Eddie Lang
• Eddit Condon
• Gene Krupa
• Jack Teagarden
• Coleman Hawkins
• Frankie Trumbauer

While McKenzie wasn’t a virtuoso solist on the kazoo, he was a very fine singer whose recorded legacy has held up very well. You can hear 50 of his tracks at the excelent site redhotjazz.com.
