Also collaborated others musicians such as Lara, Tomas "Twags" Salter, Shelly Peiken, Mónica Vélez, Kenny Aronoff and Eric Avery.

Three other songs are from the recognized producer Carlos Lara, who is considered to be the creator of RBD and has collaborated with musicians such as Lynda Thomas and Ricky Martin.

The album was mastered at the Los Angeles, California studio Igloo Music under the direction of Gustavo Borner,[8] who has worked with well-known artists such as Diego Torres, Ricky Martin, Sin Bandera, Phil Collins, Plácido Domingo and N'Sync, as well as working on the motion picture soundtracks of Rush Hour 2, Miami Vice and Finding Nemo.

Nadha's fifth track, "Disfraz", is an emo pop song that addresses the topic of homosexuality from the perspective of a person with this sexual preference.

The alternative rock cut, "Cicatriz", includes strong guitar and drum instrumentation with a powerful vocal performance by Kudai’s female members Gabriela Villalba and Barbara Sepulveda, and talks about a person's depressed state.

The album's eleventh track, "Abre Los Ojos", also drew comparisons to early RBD productions due to its lyrics.

One month later, the band presented a preview of "Lejos De Aquí", the lead single from Nadha, on Radio Disney Latin America.

[11] The music video for the single, directed by Juan Pablo Olivares, entered heavy rotation across MTV Latin America, and it shows the members of Kudai with a futuristic and minimalist style.

[13] Kudai made their first promotional tour in the United States, visiting some cities in Texas during April 2008 like Houston, McAllen, San Antonio and Dallas.

[14] Early September 2009, Kudai filmed the video for the second single “Nada Es Igual”, a power pop ballad that reached the top ten in the charts of different countries such as Argentina, Chile, Costa Rica, Guatemala and Panama.

On October 23, 2009, a Kudai TV special premiered on Boomerang in the Boombox en Estudio music segment, directed by Diego Alvarez and produced by Aldo Ballesteros.
