1999–2002: Ciao

Pablo Vega, a Mexican producer and manager based in Chile, formed a children's group called "Ciao"^[2] late 1999.^[3] Initially, the group included Nicole Natalino and Tomás Manzi, and later, Bárbara Sepúlveda, who auditioned, and replaced another girl who could not continue within the musical project. Finally, the group was formed by the fourth member, Pablo Holman, who joined "Ciao" by a reference, because his father is a well-known musician from Chile and acquaintance of Vega. The concept of "Ciao" consisted of a group of children each represented by a color –Pablo, blue; Barbara, fuchsia; Nicole, purple and Tomás, green – who performed Italian pop hits.

Ciao released their first and only album studio, El Poder de los Niños, early 2002 by EMI Odeón Chilena.^[4] Two singles from the album were promoted on Chilean radio stations, "Será Porque Te Amo" and "Mamma María", both of which contained its own music videos. For two years, Ciao made appearances on television shows, until the group transitioned into a teen concept.^[5]

2003–2005: Foundation of Kudai, and Vuelo

The group began accepting song submissions and concentrating on performing original material in hopes of breaking out of its niche market. Their reinvention was complete after changing their name from CIAO to Kudai, which is derived from the Mapudungun (native Chilean language) word kudau, which according to the bandmembers means "young worker." In 2004 the group, now composed of four vocalists (Pablo, Tomas, Barbara, and Nicole), released its debut record, entitled Vuelo (Flight). Thanks to a string of successful singles, Vuelo soon achieved platinum record status. The group began its steady climb to the top with a Best New Artist nomination from MTV Latin American video music awards for their music video from the first single "Sin Despertar", quickly escalated to the first places of Chilean music rankings. Soon, they released their second single, "Ya Nada Queda", which achieved great success as did their third single, "Escapar". Vuelo went platinum in August 2005. Kudai was nominated for Best Artist—Central Region and Best New Artist—Central Region in the MTV Video Music Awards Latin America 2005. They released their first DVD, which included their 2004–2005 Tour, in September 2005 called En Vivo - Gira 2004–2005. The album was released in Mexico in July 2006 with a different cover with the same tracks. The album sold more of 500,000 copies worldwide.^[6]

2006–2007: Sobrevive, their second studio album

The album was released in 2007 in Mexico and sold more than 350,000 copies worldwide.

This album was the last record on which Nicole Natalino sang. She left the group due to personal problems. After the departure of Nicole, Gabriela Villalba replaced her and re-recorded the album featuring Gabriela's voice; this was released on September 26, 2007 in Chile. The album represented a drastic change in their style with a heavier sound and darker lyrics about anorexia, teenage pregnancy, drug addiction & suicide.

The video of the single features Nicole before her departure and also hit the #1 spot on many music video channels and programs in Latin America and reached #1 on MTV Latin America's TRL Los 10+ Pedidos in Argentina and Top 20. She became a permanent member of the group, and now contributes to the group's excellent trajectory. The second single is "Llévame" and this performs at all Gabriela Villalba. The video also features the new member and it was filmed in the Andes in Chile. This version of the record was promoted in Latinamerica. In addition to replacing Nicole, the track listing also changed a bit. The song "Si He Tocado El Suelo" was removed and a new one titled "Tú replaced it"

They also performed the theme for the MTV Latin America's show, Quiero mis Quince (English: My Super Sweet 16). On October 19, 2006, the group won the MTV Latin American video music awards award for Best Central Artist and Best Pop Artist, which they dedicated to both their fans and Nicole.

2008–2010: Nadha

Kudai music video making of in 2008

Towards the end of 2007 they moved to Mexico to launch their international career and left Chile. Kudai closed their career in Chile when they played in the Festival de Viña del Mar, which was their last presentation in the country until now. Kudai has revolutionized punk and rock music in Latin America. They recorded their third studio album called Nadha. The album has 12 songs, of which six were written by producer Koko Stambuk (ex-musician of Glup!). Three other songs are from producer Carlos Lara, who is considered to be the creator of RBD and has collaborated with musicians such as Lynda Thomas and Ricky Martin. Cathy Lean (Ex-Mal Corazón), from Chile, also wrote two of the album's songs. Kudai chose to interpret the songs of Alanis Morissette and her band's bassist Eric Avery (ex-Jane's Addiction). The album was mastered at a Los Angeles studio, Igloo Music, under the direction of Gustavo Borner, 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.^[7]

Kudai band member Gabriela Villalba has said that this album is a turning point in Kudai's musical career:

"Now is the time that Kudai needs to show and prove many things because if we remain the same, we will be categorized as the teen band that will never grow. I feel that this third album is a very decisive stage for Kudai. We are going to fight to rid ourselves from the title of "the band that wants to be popular" and actually present good material."

Rumors say Kudai might be performing in World Peace One in 2008. The group might be playing in Berlin, Germany, though other sources claim they might be playing in Puerto Rico. They appeared also in one episode of Skimo and performed "Déjame Gritar".
