The group was founded just seven months before its audition.
Mariachi Nuevo Estillo AVM's audition in Episode 802 consisted of performing mariachi versions of "Low" and "Sexy and I Know It." Howard Stern, Heidi Klum, Mel B, and Howie Mandel all voted "Yes," sending the group to the Vegas Round.
Mariachi Nuevo Estillo NVM was sorted into the "Music Groups" category in the Vegas Round. The group's performance in Episode 808 was not televised (the group was sighted briefly watching Forte perform), but its performance was not strong enough for the judges to send it to the Quarterfinals, eliminating it from the competition.
