These videos were presumably recorded at an event called Picolandia also known as jaripeos, on July 16th from 6p.m.- 1a.m. These events are held at the Sports Arena Drive in Pico Rivera, CA (Los Angeles.) On July 16th Picolandia hosted their summer fest event where it contained 5 Bandas, 5 Nortenos, and 5 Tamborazos. Typically jaripeos are held at arenas in which spectators watch charreria consisting of horses, bulls and calves being ridden or lassoed (rodeo), there is also food and alcohol stands, raffles, regional music and bands. On the last video you are able to witness someo known dance steps pertained to regional music (of course there is more to it.) 

This last video ft. my sister and father, was taken at my house in El Cajon, CA, where we hosted a surprise, graduation party for my sister. She had recently graduated from Midland University, located in Fremont, Nebraska, where she had received a full-ride scholarship; due to Soccer and her good grades. The year where everyone experienced hardship due to COVID19, my sister had a breakthrough moment with her Bachelors Degree; and of course we had to celebrate such a moment. On 4th of July, 2020 we hosted her surprise party where I had the privilege to contract a norteno named La Escuela Nueva (some good friends of mine group.) You guys are able to find them on Instagram under: @grupolaescuelanueva, and are also able to contract them for any special occasion.
