The former Elefante frontman has been plagued by rumours of his addiction issues for months and now he has faced up to his troubles in a candid letter to the Society of Authors and Composers of Mexico (SACM), of which he is a boardmember.

In his note, 43-year-old Barba reveals he began drinking heavily from the age of 18 and he only quit his boozing in July (15), when he could no longer continue with his destructive behaviour.

Describing his moment of realisation, he writes, "I was lost, but I learned to live with myself, I kissed her madness, I tangled with delirium and one night I found myself on the precipice and flew, and fell, and time stood before my eyes and I understood that faith is the key to life."

Barba reveals he "walked away from the noise and the news" and went into hiding to work on his recovery in the Mexican town of San Cristobal de las Casas.

The singer is still continuing his treatment, but insists he is feeling "refreshed" and "revolutionized" as he looks to rebuild his career in the near future.
