After working for much of 2005 on new material, Cerati released "Ahí Vamos" ("There We Go") in April 2006. Co-produced by longtime Soda Stereo collaborator Tweety González, "Ahí Vamos" marked Cerati's triumphant return to guitar rock. For the recording of "Ahí Vamos", Cerati was accompanied by longtime collaborators, Richard Coleman, Fernando Nalé, and many others. The album was mixed by Héctor Castillo, a prolific engineer whose credits include David Bowie, Lou Reed, and Aterciopelados, to name a few. The album was mastered by Howie Weinberg at Masterdisk in New York City. "Ahí Vamos" was lauded by fans and critics alike as a return to form for Cerati. The "Ahí Vamos" tour traveled through Latin America, the Caribbean, the United States (where he played in New York's Central Park), Spain, and on 12 October 2006, Cerati played London, England, for the first time in his career.
