Before the formation of The Pamplonesa City Hall official band, there were three military bands that had the task of creating the musical "parade" in Pamplona. These were the Regimiento Almansa noº18, Regimiento de América noº.14 and the Regimiento Constitución noº29. In 1919, Silvanio Cervantes, Manuel Zugarrondo and Vicente Sádaba proposed the idea to the City Hall of creating a band made up of a mixture of military musicians and other civilian musicians from the city. The City hall accepted the proposal and let a room to them at the Music Academy. However, very soon there were some problems about who would be in charge of the band and the City Hall withdrew the premises. The musicians went with their instruments to the Paseo de Sarasate Avenue in protest and soon they were given new premises at the school in Compañia Street.
On 24th of September, 1919, the "Pamplonesa" band was formed with Vicente Sádaba as first president, Manuel Zagarrondo as vice-president and Silvanio Cervantes as conductor. There were a total of 37 musicians in the band and its official name was The Pamplona Music Band. The first performance took place on the 11th of October when the band marched through the streets playing a pasadoble and a jota. The band was first contracted by The City Hall for Sanfermin fiestas in 1920. They took part in all the events organized in the street; the txupinazo opening rocket, the Riau-Riau on the 6th, the procession on the 7th and the early morning Dianas ...they even played some afternoons in the La Taconera park at The Bosquecillo.
