Mariachi other music into their repertoires, including waltzes and polkas. It also required them to play in public venues. From the late 19th century to the 1930s, Mariachi groups were semi-professional. In the early 20th century, U.S., record companies began actively recording rural music in other parts of the world. One of these as a recording called Cuarteto Coculense by Columbia, Edison and Victor in 1908 and 1909, recognized as the “first” mariachi recordings. The music also gained attention in Mexico City when a wealthy hacienda family brought an early Mariachi from Cocula to play for President Porfirio Díaz in 1905.
MARIACHI MARIACHI MARIACHI, the Mixed Apparatus for Radar Investigation of Cosmic-rays of High Ionization, is an apparatus for the detection of ultra-high-energy cosmic rays (UHECR) via bi-static radar interferometry using VHF transmitters. MARIACHI is also the name of the research project created and directed by Brookhaven National Laboratory (BNL) on Long Island, New York, initially intended to verify the concept that VHF signals can be reflected off the ionization patch produced by a cosmic ray shower. Project emphasis subsequently shifted to the attempted detection of radio wave reflections from a high energy ionization beam apparatus located at BNL's NASA Space Radiation
