Chalino Sanchez, a native of Sinaloa, Mexico, also helped popularize narcocorridos. He sang embellished first-person accounts of shootouts with police, immigration, murder and survival that became popular, especially in southeast Los Angeles, in the late 1980s and early 1990s.

But while the trapcorrido musicians of today grew up hearing corridos, and could relate to some of the themes, their lived experiences were very different. They grew up in metropolitan California cities. They listened to hip-hop and rap music. They wear Air Jordans, Gucci and Balenciaga. Rap culture was a formative part of their upbringing.

Jose Leon, known as Mint, designs clothing for Arsenal Efectivo and other trapcorrido groups. He combines expensive fashion with urban street wear — embroidered jackets and expensive athletic shoes.

“This movement is about something different,” said Mr. Leon, 33, minutes before Arsenal Efectivo took the stage in Inglewood. He called it a trend born of the second-generation Mexican-American experience.

“All of us grew up in places like South Central, and some of us grew up in the ’hood,” he said. “People used to wear hats and cowboy boots, but these boys don’t want to wear that anymore. They want to wear what they wear in the streets. It’s a whole new wave.”

Josh Kun, a professor and director of the University of Southern California Annenberg School of Communication, believes that corridos, as a form of music that exists along and on both sides of the United States-Mexico border, lend themselves naturally to collaboration with other genres.
