The band consists of brothers José and David Muñoz; their style includes rock, rumba, and flamenco genres.

José and David attended college for some time before quitting their studies; they worked for a factory manufacturing automobile parts for the company SEAT; the band name "Estopa" comes from the expression used by their boss to keep everybody on task, "Dale estopa a la maquina".

After playing a song for the executives at BMG Music España, Estopa was given a record deal.

Their first album, "Estopa," was released 19 October 1999 and one of its songs, "La Raja de Tu Falda," became an instant hit.

Though it did not receive such good ratings as "Estopa" and "Destrangis", it became an immediate hit with songs like "Fuente de Energía" and "Apagón".

In late 2005, the band released their highly anticipated album "Voces de Ultrarumba".

The second DVD started with a TV movie "Regreso a la española", by Andreu Buenafuente, which involved numerous interviews with friends colleagues of the Muñoz brothers.

The presenter also explained the roots of Estopa and showed a clip of their performance at the bar "La Española" in Cornellá from 27 September 2009.

The 8th album was "Esto es Estopa", released on 17 February 2014, involving acoustic versions of their most successful songs.

In June and July 2015 they released their first two singles from the album "Pastillas Para Dormir" and "Nadie Sabe".

The tour started in Bogota, Colombia and proceeded to New York, Miami, Quito, Santiago de Chile (two performances), Cordoba (Argentina), Rosario (Argentina), Buenos Aires, Malaga, Granada, Barcelona, Zaragoza, Bilbao, Valencia and Madrid.
