Yo Te Avisé! (Spanish for "I told you") is the second studio album from the Argentine Ska band Los Fabulosos Cadillacs, and was released in 1987. Having built on their experience from the first album, the band also benefited from the assistance of Andres Calamaro in production. On this album, Daniel Lozano joined the band as a guest player on the trumpet, eventually becoming a full-time member.
The album was a step forward for the band; it sold more than 250 000 copies, earning the band a platinum certification, catapulting them to a moderate fame that allowed them to expand their tour schedule to countries outside of Argentina. Structurally, the album was an evolutionary shift for the band, with a focus on more elaborate songs and the incorporation of new genres in their sonic vocabulary, including reggae and dub, seen in the songs "Muy, Muy Temprano" and "El Genio del Dub", respectively.
The singles were "Mi Novia se Cayo en un Pozo Ciego", "Yo te Avise", the permanent concert opener "Cadillacs" and "Yo No Me Sentaria en Tu Mesa", which is still played in soccer matches in Argentina.
The name of the album is a direct reference to the feeling of the band members about their success and the skepticism of the media about the band; on the matter Vicentico says:
"Is called that way because we knew it was going to be a success. Among the extramusical thing we like the most is shuting up people who doesn`t know what are they talking about... They criticized us from the beginning".
The original LP had an 11th track called "Siempre Me Hablaste de Ella" but due to a mistake in the production it missed the final product, but the lyrics were, also by mistake, included in the booklet; the song was released in the next album.
