Indeed, in a magazine interview published in 2010, Quintana revealed that in spite of his lifelong deep love of music, his initial youthful ambition was to be a writer, because as a child he was too shy to contemplate performing in public.

The influences on Sopa de Cabra's style included classic rock (the band's name was in homage to the Rolling Stones' 1973 album Goat's Head Soup), reggae, and blues, but the combination of the Catalan language and the creative originality of Quintana and his colleagues (Josep Thió, Joan 'Ninyín' Cardona, Francesc 'Cuco' Lisicic, and Pep Bosch) ensured that the band's sound was unique: authentic rock music and yet distinctively Catalan.

In 1991 Sopa de Cabra, along with three other leading Catalan bands, Sau, Els Pets and Sangtraït, took part in a major concert before an audience of 20,000 at the Palau Sant Jordi in Barcelona.

By the late 1990s and with a change of record-label, the band was again at a peak of popularity, but other circumstances, notably the grave illness of Joan Cardona, led to the decision that the group would retire at the end of 2001.

Cardona was able to make a brief appearance on stage in the final concert that was held in Barcelona in November 2001, but he died of cancer in the following January, aged 42.

In March 2011, the surviving members of Sopa de Cabra announced a single anniversary reunion concert on September 9, 2011 to celebrate 25 years since the founding of the band, and ten years since its dissolution and final performances; the demand for tickets resulted in plans for a full tour of seven concerts, three in Barcelona, one each in Palma and Tarragona, and culminating with two, on 30 September and 1 October in the band's home town of Girona.

The songs were all taken from the existing, classic repertoire of Sopa de Cabra, and the line-up was almost the same as that of the late 1990s, namely Josep Thió, Cuco Lisicic, Pep Bosch, Jaume Soler and Eduard Font.

There was one addition; the guitarist, singer and songwriter Xarim Aresté, leader of the band Very Pomelo and representative of a younger generation of Catalan rock music, joined Sopa de Cabra.

He has worked with many significant figures in Catalan music, including Francesc Bertran, Quimi Portet, Albert Pla, Pep Sala, Amadeu Casas, Pascal Comelade and the group Gossos.

In the first half of the concert, Quintana once again appeared with the old Sopa de Cabra line-up, performing Camins, one of the band's most famous songs.

Quintana's stage presence remains as confident and energetic as in the old Sopa de Cabra days, and the collaboration with Xarim Aresté and a very talented band consisting of Sergi Carós, Joan Barbé, Ricard Sohn and Ermen Mayol has created a new force in Catalan popular music.

A special open-air concert for a small invited audience took place at the great Graeco-Roman site of Empúries a few days before the record went on sale, and was filmed by the Catalan television Channel TV3.

The songs on the 2015 and 2020 albums that have now been added to the band's repertoire are all by the same songwriting team as the majority of those in their earlier catalogue, with music by Josep Thió and lyrics by Gerard Quintana.

The magical power of music also enters into the story, and the song that assists Jordi when he finally encounters the dragon is a real one, written and performed by Quintana and Aresté, that can be downloaded via the publisher’s website or by way of a QR code printed within and on the back cover of the book.

[19][20] In 2014, Quintana took the lead part in a short film, written, directed and produced by Mateu Ciurana, entitled Diògenes, el gos (Diogenes, the dog).
