For 50 years, the taco has been a staple of American life. It's in school lunches and Michelin-star restaurants. It even helped launch the food truck craze. So how did the taco come to loom so large in American bellies?
There is a music store for sale in Los Angeles. It has old, sagging shelves stuffed with hundreds of thousands of recordings, from wax cylinders to 8-track tapes to LPs and CDs. The man who has owned the business since 1962 is Murray Gershenz.
"I wasn't earning enough money to support my family, so I decided to get some extra income by putting my record collection up for sale," Gershenz tells NPR's Scott Simon. "I opened the store, built some shelves with the help of a rabbi friend of mine and, little by little, the music took over."
