Polymarchs - The Beginnings (1980 - 1984)

1984)

Marco Antonio Silva De La Barrera, who was Apolinar's nephew, wanted to join the family business. An avid dancer in high school, Marco Antonio (who was nicknamed "Tony") was fascinated with the Disco music scene and wanted to join Polymarchs. With the departure of Ruelas, Tony ultimately dropped out of high school and joined in as the new DJ of the collective. Apolinar also incorporated a "ballet" or dance team into the collective with live dancers on stage and put Tony in charge of choreography.

By this time, Polymarchs had already branched out to numerous suburbs of the city performing in parks and halls, packing many of them well over capacity. Mary recalls in an interview that when she was working the gate one night, a large group of people rushed the gates and toppled the booth with her inside. Around this time, it is believed that Mary ultimately left the collective to form her own called "Rhamses". The reason for Mary's departure is not known, but the two collectives, Rhamses and Polymarchs were often seen headlining shows together well into the late 1980s.

In the early 1980s, Disco music gave way to Hi-NRG and Italo Disco which proved to be popular in Mexico City and Polymarchs sought to innovate the dance music scene in Mexico City by booking out large concert halls and sports arenas to host its massive productions. Larger venues also allowed the SONIDO to get in touch with popular disco stars such as Gloria Gaynor and Sylvester James to come to Mexico City and perform live in front of thousands of people, opportunities which disco stars couldn't achieve in other countries at the time. In anticipation for these events, street teams blanketed the city with promotional fliers and posters, many of which are deemed as collectors items to this day.

Mexico City radio stations also began to take note in the SONIDO's success and invited Tony Barrera as a guest DJ numerous amounts of times in many of the station's weekend prime-time slots. Music enthusiasts recorded the radio shows on cassette tapes and were impressed by Tony Barrera's DJ mixing abilities. Many of these tapes are considered rarities.
