Many of the acts booked in Vegas for Mexican Independence Day week sing in Spanish, but are not actually from Mexico. Caifanes is not only Mexican, they’re one of the pioneers of modern Mexican music, going back to the mid 1980s. They were heavily influenced by that decade’s British and American rock, and combined them with touchstones of traditional and modern Mexican music. Ultimately, they became one of the forefather acts of the rock en Español movement. They’ve been here before, but it’s great that they’re being counted among the many live music acts here for the big mid-September holiday stretch.
