These mariachi musicians developed new practices, such as performances in plazas and restaurants. However, it also continued its more traditional venues such as serenades, and performances at major family events. During this time, the Mexican government
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
