In November 2004, after Marcos Collado and Antonia Ferrà's sudden -though not unexpected- success, a new band called Dog Party was born. Dog Party was the result of Marcos Collado and Antonia Ferrà's alliance with two top musicians, Dani Pi (bass player) and Rubén García (drummer). The repertoire selected by Dog Party was stronger and more powerful than that of the duet, being Scott Henderson a great influence. Even the name of the band is a tribute to that musician.

Antonia led Dog Party until mid 2005, when the musicians decided to continue as an instrumental band. However, Antonia still works with Dog Party 's musicians, Marcos Collado being the guitar of one of Antonia's duets. She also plays with Rubén in Smile of Silence, a band which was born immediately after Antonia left Dog Party together with guitar player Omar Lanutti and bass Juanan Torrandell.

Superstition was a young band formed by Antonia Ferrà (voice), Miguel Porcel, (guitar), Iván Palacios (bass) and Marcelo Palmeri (drummer). Created during the first months of 2004, Superstition chose a repertoire full of cover versions of popular songs (from Shakira to Guns n'Roses, from Scorpions to Bon Jovi) which ensured the amusement of the audience. However young, Superstition was quite hardened in live appearances; their music was enjoyed in pubs such as Motown, Tonic or Tabu, in Gomila (Palma), in Carrer de Nit (Son Sardina) and in village celebrations like Caïmari or the district Son Armadans, in Palma.

All the reviews and comments were invariably positive. The article published in a local newspaper emphasised the versatility of the band: "Paying a tribute to some great (and not so great) hits, travelling through each and every style -rock, blues, soul, pop, heavy metal...- the experienced musicians (...) have offered an eclectic selection of cover versions."
