Perenne translates to "perennial" or "everlasting". It's a less common, more poetic word than simply saying "forever" or "always", making it stand out.
In "EL VALLENATO ES SILVESTRE", Silvestre Dangond uses perenne to describe his feeling for vallenato music: "El sentimiento es perenne" (The feeling is everlasting). This emphasizes the deep, enduring nature of his passion and connection to the genre, suggesting it's a love that will never fade.
"El Vallenato Es Silvestre" is Silvestre Dangond's tribute to the genre that shaped his career, and it plays on his own name along the way.
He sings about vallenato as something untamed and everywhere at once: it doesn't fade like a trend, it stays because it is felt. Throughout the song he calls out the musicians bringing it to life, including accordion player Marlon and the rest of his band, celebrating vallenato as a real source of pride for Colombia.
