1990-2004: Beginning and rise to fame

Eddie Dee was born Eddie Alexander Ávila Ortiz on April 26, 1977 to his mother Diomaris Ortiz and father Eddie Ávila. He began singing and composing songs at an early age before beginning his musical career in 1990, when he started to appear on television shows. His first encounter with fame was in 1987 when he was already famous in his neighbourhood because of his rapping. In 1991 he was one of the dancers in the Puerto Rican propaganda El Sida Está Cañón, led by the singer Ernesto Morales, a message to prevent AIDS. In 1993, he released his debut album Eddie & The Ghetto Crew. Following the album, he began gaining popularity within Puerto Rico by collaborating with other artists.^[4] In 1994 Eddie participated on a music video for Straight From The Ghetto, a mixtape by the producer DJ Guichy, being Edde's first participation on a music video. Eddie Dee became popular with the 1997 single "Señor Oficial," from his first compilation album Tagwut, which detailed "the injustices that young Puerto Rican men suffered at the hands of the police." It was a commercial success reaching number one in Puerto Rico.^[3] The album gained him a "Puerto Rican Rap and Reggae Award for Best Lyrics" the same year.^[4] In 1999 he helped a new rapper by supporting his work and recording with him on the song "En Peligro De Extinción", which was part of the track list of his next studio album: El Terrorista De La Lírica (which also includes the posthumous appearance of Frankie Ruiz, a famous American salsa singer, who died in 1998). That rapper was Tego Calderón at his very early beginning in the music industry, and in 2003 he gained international popularity after his first studio album, El Abayarde, which sold 300.000 copies worldwide.

2006-present: El Diario and musical inactivity

In 2005 was announced his next studio album: El Diario, which was going to be released in November 2007. In that year was released a 10 track-long free mixtape titled The Final Countdown, but El Diario wasn't released. In 2009 was announced another mixtape: 180 Grados and Eddie said that his studio album was going to be released, and also said that it wasn't published in 2007 because he wasn't sure of his album quality as to music. Neither El Diario and 180 Grados have been released, but both also haven’t been confirmed to be canceled. His work has been decreased after El Diario's postponement, releasing just two singles between 2009 and 2010, writing Jowell & Randy's "Un Cambio" in 2010 and Plan B's "Te Dijeron" for Pina Record's La Formula in 2012, and collaborating in Alexis & Fido's "La Trampa" (2011) and Wisin's remix of "Sistema" (2013), which was his last participation in a song, either being him as principal or guest artist.

After two years of public inactivity, Eddie Dee appeared as a guest artist in Tego Calderon's La Trayectoria concert in the famous Puerto Rican Coliseum, performing "Los 12 Discípulos", "En Peligro De Extinción", and "El Bueno, El Malo Y El Feo" alongside Calderón and Vico C.
