Over 1,000 mariachi musicians from across the country are converging in San Antonio this weekend for the 22nd Annual Mariachi Vargas Extravaganza. All the fun kicked off Thursday at the River Center Mall Lagoon.

People came from throughout the country to hear the youngsters hit the right notes.

"I've got friends down here. We've talked about it and said this is the time to leave frozen Colorado, come to beautiful San Antonio, and come to the mariachi festival," said Don Moore of Canyon City, Colorado.

Others, like Abigail Flores from Philly, have been volunteering with the festival since 2013 to make sure the kids don't fall flat.

"I help the groups to get ready to go down into a room where they can kind of get together, get ready, get pumped up, practice a little bit, and then we bring them up on stage to get ready to actually perform and compete," Flores said.

In all, 51 mariachi groups from across the U.S. will battle it out over the next few days in what is called the toughest national mariachi group and vocal competition in the nation.

One of those groups is a collection of sharply dressed middle schoolers from Rio Grande City, Texas.

"We have 14 kids in the mariachi, 14 kids ranging from 6th to 8th grade," their teacher Diana Salinas said.

While they were tuning up, KENS 5 asked if they were nervous or excited.

"Kind of both. In the middle," 7th grader Victoria Garza said.

The vocal competition begins Friday night at 7:30 at the Lila Cockrell Theatre. For more information on tickets and the weekend schedule just click visit their official website here.
