1996–2002: Solo work and musical theater debut

Her fourth album was released in 1996 and was called Primeiras Águas (First Water), which yielded the hit song "Avenidas" written by Clara Pinto Correia and Rui Veloso. That year she also participated in Filipe La Féria's children's musical Jasmim ou o Sonho do Cinema (Jasmine: The Dream of Cinema). In 1999, Anabela worked with La Féria again, starring in the musical Koko. She released another album that same year, heralded by HMV Japan as "the new generation of fado,"^[9] called Origens (Sources).

In 2000, she recorded four tracks with the Galician musician Carlos Núñez for his album Mayo Longo (Long May),^[10] and participated in the promotional tour, which lasted two and a half years and took her around the world. Returning to Portugal in 2002, she continued her association with La Féria, playing protagonist Eliza Doolittle in the Lisbon production of My Fair Lady.

2005: Experimental album

In 2005, she released her first album in six years, which was an interpretation of poems called Aether. With the help of Carlos Maria Trindade,^[11] she interpreted the poems of Portuguese writers Florbela Espanca, Fernando Pessoa, Manuel Alegre and José Carlos Ary dos Santos. She also released a Spanish version of her album on Resistencia Records.^[11] In March 2006, she performed three special concerts in Spain^[11] and two in the Azores,^[12] performing some of the works on the Aether album.

2006–present: Música no Coração, Jesus Cristo Superstar and Amor Sem Barreiras

In 2006, Anabela and popular singer Lúcia Moniz took turns playing the part of Maria von Trapp in Música no Coração (roughly translated as Music in the Heart), the Portuguese production of The Sound of Music at the Teatro Politeama in Lisbon. This was a continuation of Anabela's working relationship with La Féria, as he directed the production.

In December 2007, the show was taken on the road to Porto, where Anabela reprised her role at the Teatro Rivoli with Wanda Stuart.^[13] The musical celebrated its 500th show in Portugal in April 2008^[14] and finished its run on 4 May 2008.

Taking a break of less than a month, Anabela returned to the stage on 30 May 2008^[15] at the Teatro Politeama, in Lisbon, working again with La Féria. She stepped into the role of Mary Magdalene in Jesus Cristo Superstar,^[16] the Lisbon production of Jesus Christ Superstar, taking over the part from Sara Lima. For the entire month of August 2008, Anabela and the entire company performed the musical in Portimão, in the Algarve.^[17]

As of 28 November 2008, she is participating in La Féria's newest musical production, Amor Sem Barreiras, the Portuguese adaptation of West Side Story, at Lisbon's Politeama. Anabela plays the role of Anita, the sensual and confident woman whose boyfriend is the leader of the Sharks, a gang composed by the first generation of Americans from Puerto Rico. Again, her part is performed in turns with Lúcia Moniz.^[18] Talking about her character, Anabela confessed it is her "career's greatest challenge. Completely different from what I have been doing so far." She further explains that "the attitude, poise and voice are very distinct from mine and clash with the roles of young innocent girl that I am used to performing."^[19]
