Desenfundo means "I unsheathe" or "I draw (a weapon)". It's a dramatic and action-oriented verb that immediately brings to mind images of a duel or a battle.
In this song, Gera MX uses it metaphorically when he sings, "Desenfundo mi espada, peleo con mis demonios" (I unsheathe my sword, I fight with my demons). This powerful imagery conveys his internal struggle and his readiness to confront his personal challenges, making it a memorable and impactful word choice.
Gera MX's "El Músico" is a really honest look at the life of a musician and the sacrifices that come with it. He's chasing his dreams, and he knows it's going to take up more and more of his time, pulling him away from his partner. He even admits, "Olvida el matrimonio y la casa en Barcelona" [Forget marriage and a house in Barcelona], showing how dedicated he is to his craft, even if it means letting go of traditional relationship goals.
He grapples with the guilt of not being present, saying, "Claro que pido disculpas por las noches que aparezco pidiendo respuestas de celos que no merezco" [Of course I apologize for the nights I show up asking for jealous answers I don't deserve]. It's a candid confession about the strain his passion puts on his relationships, and how he feels misunderstood. He knows he's always been this way and will die this way, as he repeats, "Yo siempre he sido el mismo y así moriré, recuerda" [I've always been the same and I'll die this way, remember].
