Mammut, formed in early 2005, was founded by lifelong friends Diego Boulocq along with drummer Mauricio Moscoso and bassist Pablo Quiroga; bandmates who had previously played together in the nationally recognized Cochabamba-based band H3O (1998-2005).

At the early ages of 16 and 17, the members of H3O edited their first album aptly titled “Solos” (Alone), which had moderate success in the local scene and served as a starting point for a promising career nationwide. It wasn't until their sophomore album “Anzuelo” (Hook), which was released in 2003, that H30 literally “hooked” the masses, flourished musically and were catapulted commercially, the latter thanks in large part to the unprecedented success of their single “Sr.Chichero”. That same year the band was recognized with a golden record due to the increasing sales of the album “Anzuelo” and a large amount of promotional singles that were on constant rotation throughout national radios.

On 2004 H30 was officially recognized as one of the biggest bands in Bolivia and continued winning several awards. Extensive touring for large audiences allowed the band to play alongside such industry heavyweights as Diego Torres and Los Auténticos Decadentes among others. The same year the band signed a contract with one of the largest beer companies in the country (Taquiña) to promote it's product by writing and recording the promotional jingle as well as performing in an exclusive nationwide commercial to endorse the beer.

Also in 2004 Diego Boulocq and Mauricio Moscoso earn nominations for best leading vocals and best drummer in a band, respectively. The “Premios de la Concordia” awards also recognized H30's effort by making them recipient of three awards, which were Breakthrough Artist, Band of the Year and Best Video for their single “Quédate”. By the end of the year the band had already released their third album (and first one recorded live) alongside their first DVD, which showcased an acoustic arrangement of most of their previously released songs, all performed in Cochabamba on October 2004.

Several commercial hits and jam-packed crowded performances after their foundation in 1998 H3O finally decide to bring an end to their careers in 2005 for several motives.

It was at this stage that the long foreseen and postponed project titled Mammut was  officially conceived as a band by the remaining members of H3O; the main purpose being the full realization of the aforementioned bandmates' potential, which translated into a more polished and modern sound. Halfway through 2005 the newborn Mammut independently began to work on their first album.

 Recording of the self-titled debut album took place throughout 2006 by the hand of Mutante Studios' owner and producer Cacho Romero, who actively participated in the co-production of the record. Currently the band is dedicating it's time to promotional activities which include the release of the music video for their first single “Cada día”, which was directed by the critically acclaimed director Martin Boulocq. With these and many other activities in agenda, 2007 promises to be a fruitful year for Mammut.
