One of the types found in the United States is the North American "Polish-style polka," which has roots in Chicago, with large Czech and Polish minorities; two sub-styles are "The Chicago Honky" (using clarinet and one trumpet) and "Chicago Push" featuring the accordion, Chemnitzer and Star concertinas, upright bass or bass guitar, drums, and (almost always) two trumpets. North American "Slovenian-style polka" is fast and features piano accordion, chromatic accordion, and/or diatonic button box accordion; it is associated with Cleveland. North American "Dutchmen-style" features an oom-pah sound often with a tuba and banjo, and has roots in the American Midwest. "Conjunto-style" polkas have roots in northern Mexico and Texas, and are also called "Norteño". Traditional dances from this region reflect the influence of polka-dancing European immigrants. In the 1980s and 1990s, several American bands began to combine polka with various rock styles (sometimes referred to as "punk polka"), "alternative polka", or "San Francisco-style".
