Formed in 1997 with a sound of powerful and overwhelming rock, they began to play several underground stages.

In 1998, they recorded their first self-titled album "MAD", and harvesting very positive critiques they obtained fair radio airing.

Around that time, they were invited to play at several rock festivals organized by the "Rock and Pop" FM radio station and they recorded two songs for a 4K Record CD compilation.

In 2000, MAD was chosen to be the band for Eric Singer, KISS' drummer, at his concert for the Kiss Exposition held in Buenos Aires.

In the same year, one of the most important breweries in Argentina, "Cerveza Quilmes", chose MAD to play twice in the same year, as a headliner, in the well-known "truck/rolling studio" in Mar del Plata City and in one of their two shows in Buenos Aires.

In January, 2001, MAD played for 50,000 people in the Monsters Of Rock Festival, with Iron Maiden, Rob Halford and Queens of the Stone Age at the Velez Stadium.

They continued playing very often at Cemento, the Buenos Aires' temple of rock and roll, offering perfectly produced shows, consolidating the band as one of the most important of the moment.

In the middle of that year they entered the EL PIE recording studios to record "En llamas", their second album, produced by 4K Records/Sony Music. Very soon, the first single, "Pajarito on the rocks" became a big hit, for which a videoclip was made.

In 2004, guitar player Nicolas Barreiro jumped into the new lineup, and the band recorded its third album produced by Adrián Taverna (Divididos, Attaque, Redonditos de Ricota, Soda Stereo, Riff, Gustavo Cerati, etc.); "Seguí la flecha" introduced a powerful, direct, and strengthened band. From this album, several radio hits are born, like "La rueda", "Imperdonable" and "El postre", a song for which another videoclip was made.

In December, 2005, MAD played its first electric/acoustic show, which was recorded in pro-tools, to be released in the following months as the long awaited live album "Laiv in Once".

In January, 2006, the band offered another powerful and well-attended show at the Cosquin Rock Festival, by Lake San Roque, in the Province of Cordoba.

In April, the drummer "Vasco" re-entered the band, and "Gato" finally took control of the lead vocals. Now, with this ideal lineup and an almost 10-year history of a precise and overwhelming sound, each show of MAD is a sample of pure rock.

In November, 2006, MAD flew to Europe for the International leg of its "M10" tour, celebrating 10 years of rock by playing at Madrid, Barcelona, Canary Islands, Paris, Bilbao and many other cities...

On Abril 2007 the new live recorded album“LAIV IN ONCE” was released ,and it was mastered in New York by Andy Vandette, well known for his works with Led Zeppelin, Nirvana, U2, Motley Crue, Pearl Jam, Tool, Bruce Springsteen, etc.

On June 2007, MAD was declared by the Argentine's Foreign Office as "Band of Official Cultural Interest".

The band's management is English speaking.
