In 1977, after a series of trips abroad, Casal returned to Spain, where he signed a recording contract with Philips when Spanish music lovers were looking for a substitute for well-loved crooners Nino Bravo and Bruno Lomas.

[2] After breaking his recording contract, Casal threw himself into painting until 1980, when he returned to music, producing other artists, such as Goma de Mascar or the Obús, the first heavy metal group in Spain.

In 1981, he released his first solo effort, Neocasal, produced by Julian Ruiz, which contained the hits "Champú de Huevo" (Egg Shampoo) - his first Number 1 - and "Billy Boy".

He also continued to produce records for groups, such as Azul y Negro and Obús, and collaborated with filmmaker Pedro Almodóvar, financing the production of the film Laberinto de pasiones (Labyrinth of Passion) which yielded certain famous elements of Casal's appearance, such as his red jacket, originally worn by Imanol Arias.

[4] In 1983 the release of Etiqueta Negra, consolidated Casal's position as a major player on the Spanish music scene with the success of "Embrujada" ("Bewitched") and "Póker para un perdedor" ("Poker for a Loser").

The following year, he released "Hielo Rojo" ("Red Ice"), from which appeared the hit single, "Pánico en el edén" ("Panic in the Garden of Eden").

Casal and other three people were at a nightclub after they have had a dinner and went to Tino's house in order to bring microphones with them to a recording studio they wished to visit in Pozuelo, when, due to the rain, the driver of the Opel Corsa lost control of the car and crashed violently into a lamp post after sliding down through muddy soil.
