This encompasses various styles of music, including blues, jazz, pop, ragtime, and country.  I’m gonna list some extra words for the benefit of search-breadth: trad jazz, traditional jazz, hot jazz, jug band, vocal harmony, tin pan alley, vaudeville, vitaphone, vintage, americana, delta blues.  I present shows in different styles by having different instrumentation in my band if I have a band, and by choosing repertoire that is appropriate to the theme.
