Uno

'Uno' is a seminal Argentine tango first released in 1943, composed by Mariano Mores with lyrics by Enrique Santos Discépolo. Mores, a virtuoso pianist, brought a highly polished and dramatic orchestral style to the genre. The song immediately became a defining hit of the golden age of tango.

The song features an intensely emotional vocal performance and deeply lyrical narrative focusing on the bitter regrets of lost love and life's disappointments. Discépolo’s lyrics explore the tragic realization that a passionate love affair has left one wounded and cynical. It is widely considered one of the most melodramatic masterpieces in tango history.

The original 1943 recording was heavily censored by the Argentine government because the opening line contained the word 'corrompido' (corrupt), which officials deemed inappropriate. Enrique Santos Discépolo had to rewrite the lyrics to say 'desconocido' (unknown) to get the song played on the radio. The uncensored version was only fully restored to the airwaves years later.

Unlike traditional bandoneón-heavy orchestras, Mariano Mores anchored 'Uno' with sweeping, virtuosic piano melodies and lush string arrangements. This gave the track a grand, almost cinematic orchestral feel that set it apart from its contemporaries. His highly polished style helped modernize tango music for mainstream international audiences.
