She was Carmen at the Royal Opera Covent Garden that spring (where the Times wrote: "Herrera's high vocal intelligence is the equal of the cunning of this Carmen. Her words are threaded in taut, sprung rhythms within an entirely secure and eloquent vocal range,") as well as at the Metropolitan Opera. including the broadcast. Just prior she was in Madrid for zarzuela during the holiday season. She sang the Verdi Requiem in Barcelona as well as concerts in China with the orchestra of Las Palmas earlier that fall.

She was Orlofsky in Die Fledermaus in her return to Las Palmas having begun 2007 at the Opéra Bastille as Giulietta in Les Contes d'Hoffmann. She also "was the rich-voiced" Maddalena in the Metropolitan Opera's Rigoletto. Earlier in 2006 she performed Carmen at La Corunia and Santander in Spain and sang a gala concert with Plácido Domingo in Puerto Rico. She has sung the title role of Luisa Fernanda in Madrid (released on DVD) and performed Charlotte in Werther in Las Palmas with a "quality of phrasing and exquisite line of singing and put her extraordinary vocal abilities at the service of the character." She also sang the Verdi Requiem at the Casals Festival. In fall of 2005 she performed Carmen at the Metropolitan Opera and repeated this in Jerez.

Other notable engagements have included: Tokyo as Dorabella in Così fan tuttte, orchestral concerts in Madrid under Jesus Lopez-Cobos, Carmen at the New National Theater, Pauline at the Teatro Real in Madrid's The Queen of Spades, Dallas' La Vida Breve, her Covent Garden debut as Suzuki in Madama Butterfly and her Italian debut at the Rome Opera as Carmen.
