The lyrics describe his nostalgia for the dirt roads, drinking water from the well, and the simplicity of life in the countryside.

The singer reminisces about having a small plot of land, four cows, a pig being fattened, and a pair of oxen pulling the plow, while his father shells corn. The lyrics also depict the daily routines of the singer's grandparents, where the grandmother makes tortillas on a clay griddle at 7 o'clock, the grandfather sharpens his machete, and they all gather to eat beans cooked in a pot over the firewood from the hill. Despite the simplicity and humble lifestyle, the singer proudly mentions his old and worn-out hat, three shirts, two pairs of pants, and worn-out sandals. He emphasizes that he is not ashamed of being poor. Overall, "Calles De Tierra" expresses the singer's deep love and longing for the rural environment, its customs, and the hardworking people who lived there.
