Big Mouth was conceived by Kepa Big Mouth in Bilbao in 2006, like a punk/rock band geared toward that rock 'n' roll classic sounds,
with punk influence. He, with Alberto Martín, and some occasional bass players, recorded the first album of the band, Letters For
A Princess, in Zombee Records. This album was produced by Big Mouth and Juan Luis Cordero.
Shortly after, the band just died.
Kepa Big Mouth was playing in another bands, and in one of them he met who later will be called Iñaki Big Mouth.
In 2012, Kepa
decided to revive Big Mouth and, to do this, he called Iñaki, and together, they began to prepare the second album of the band,We Have No Time. For that, they contacted Xabi Big Mouth, bass player who played in bands more oriented to other styles. With that
formation (the definitive formation), the band confines itself in Mr. Thief Records for recording the album at its own risk, being
its own producer, sound designer, mastering designer, graphic designer, disc manufacturer, etc.; and the project was completed in
april 2014, after a few months of hard work and shortened sleep.
Following the same philosophy, by the end of 2014, Big Mouth
confines itself again in Xiklig Records, for recording T-Rex On My Back, its third album, that began in april 2015. During the tour,
Xabi decides to leave the band to begin his own adventure without Big Mouth, and he is replaced by Javi Big Mouth who, instantly,
takes possession of the bass guitar and becomes part of the family.
In January 2017 they publish their 4th album, The Smoke Seller.
