# Mundo de Cristal

Mundo de Cristal (English: Crystal World) is the second studio album by Mexican singer Thalía, released in Mexico on 26 September 1991, by Fonovisa Records. It was Thalía's second and last album to be produced by Alfredo Díaz Ordaz, who was her boyfriend at that time and died of hepatitis in 1993. Mundo de Cristal was certified 2× Gold in Mexico for shipments of 200,000 units. The most successful singles from the album were "Sudor", "En La Intimidad" and "Fuego Cruzado". To celebrate Thalía's 25th anniversary as a solo artist, this album is available in the digital platforms iTunes and Spotify since December 2014.

## Background and production

After the success of her first studio album, which earned the artist a 2× Gold certification for more than 200,000 copies sold in less than a year, the singer was exhausted with the album promotion. Furthermore, her dissatisfaction with the countless criticisms received for her new rebellious and sensual image was notable. The singer went into depression and came to think about stop singing. Her mother Yolanda and her boyfriend Alfredo Díaz convinced her to take a vacation in Los Angeles and at that time, Alfredo proposed to marry her. The singer refuses the request but feels she was ready to continue with her musical career.
The twelve songs of this album were produced by Alfredo Díaz Ordaz, who also produced Thalía. Four songs of Mundo de Cristal were originally written for Thalía's debut album: "Sudor", "Me Matas", "Jollie Madame" and "En La Intimidad". The album includes pop rock songs such as "En La Intimidad", "Me Matas" and "Jollie Madame" and ballads like "Fuego Cruzado" and "Te Necesito". "Jollie Madame" is the first Thalía's self-penned song, and it is mentioned in the album's credits as her "first pact with music, on a May 5th". "En Silencio" is a dedication to the memory of her father, who died when Thalía was a child.
