Against the backdrop of President Trump's much-trumpeted wall, Reginald D Hunter takes a 2,000-mile road trip along the US-Mexico border to explore how romance and reality play out musically where third-world Mexico meets first-world USA.Classic American pop and country portray Mexico as a land of escape and romance, but also of danger - think of Marty Robbins's El Paso. Hunter explores the border music as it is today, much of it created by musicians drawn from the 36 million Mexican-Americans who are US citizens. The performers and their music shed a fascinating insight into the topical issues of immigration, drug smuggling and Mexican-American identity.
