[2] Cabra inherited her voice from her mother and her grandmother, Flor Amelia de Gracia, teacher, and composer, who is also featured on the back cover of Calle 13's self-titled debut album.

After recording a second song, "La Tribu", she was immediately nicknamed PG-13 by her cousin Ian Marcel Cardozo Joglar, since she was under-aged at the time, she joined the group and PG-13 is normally used to classify movies that require parental guidance for children under 13.

At only 16 years of age, she found herself singing on stage in front of thousands at the Coliseo de Puerto Rico José Miguel Agrelot, as part of Calle 13's first concert.

At that time, she had the opportunity to visit other countries and share the stage with some of her most admired artists, such as Gustavo Santaolalla, Kevin Johansen, and Susana Baca.

When she was 18, PG-13 sang at the 8th Annual Latin Grammy Awards presentation held at the Mandalay Bay in Las Vegas, as part of Calle 13's interpretation of "Pa'l Norte" which opened with PG-13 performing a solo a cappella.

[15] In November 2011, Calle 13 opened the Gala at the 12th edition of the Latin Grammy Awards with the theme "Latinoamérica" performed with a symphony orchestra arrangement by Alex Berti and conducted by Musical Director Gustavo Dudamel.

"[25] Jon Pareles of The New York Times described it as "a knowingly retro survey of Latin music's past, full of romance and a longing that can turn despondent.

"[26] Some of Puerto Rico's most prominent musicians collaborated on the album: Piro Rodríguez, Charlie Sepulveda, Bayrex Jiménez, Eduardo Cabra, Fofé Abreu from Circo, Louis García and the late Cheo Feliciano in one of his last recordings ever.

[2][33] The video for the lead single, "Odio," reenacts the Cerro Maravilla murders as a message of empowerment and solidarity in response to the aftermath of the storm.

[2][34] In a year-end essay for Slate, Ann Powers cited Almadura as proof that the format is not dead but rather undergoing a "metamorphosis", with artists such as iLe utilizing the concept album through the culturally relevant autobiographical narratives.

It incorporates iLe's love of traditional Latin American music, Puerto Rican folk percussion, and even some of the hip-hop she and her brothers used to perform in the renowned group Calle 13 when she was younger.

[37] A song, Afilando los cuchillos, (English: "Sharpening the knives") with lyrics by Bad Bunny, Residente, and iLe, was released during the Telegramgate protests.
