Dramatic nuevo-tango arrangement with bandoneon leads and rich string orchestra, male vocals. Piano arpeggios and contrabass drive a slow-burn groove that swells into sweeping, cinematic choruses. Flute and brass add color in the highs, with occasional accordion answers to the vocal. Dynamic arc from intimate, breathy verses to full-throated, passionate refrains that spiral up in intensity, then pull back to a tender, whisper-close outro.
