Sadism  was  formed in 1988.  The main idea was  to play  the most brutal music for  those days  ( death – metal ) , but a few musicians were capacited to do that. At the beginning the founder members ( J.P. Donoso and R. Roberts )  started  under the name of  ‘’black vomit ‘’, being  replaced to ‘’ sadist ‘’ and finally  as ‘’ sadism ‘’.  Months later they find the people that the band needed,  at last  sadism  was  completed.
The first works as a band were the rehearsals for its debut demo tape called ‘’ perdition of souls ‘’ , which included four songs, this was recorded on October 1989.  This record sold more than 3.000 copies in Chile as  well  as abroad.

After that, the name and reputation of the band reached a high popularity into national scene.  One year after sadism got into the studios to its second work,  ‘’ from the perpetual dark ‘’ ( demo tape with three songs ).

As the time goes by there were opportunities from different  lavels and producers to record a professional work, the debut lp ‘’ tribulated bells ‘’, the result of that was a contract with a Chilean lavel ‘’ toxic records ‘’ .  The album was made in 1992, it included nine songs and it was the first death - metal album in chile.  The promotion was with many shows around the country as abroad.

As soon as possible sadism began to work the four record, now as a professional band and of course, in a different way,  ‘’dark - side ‘’  was a very well - realized record , because  its  sound  was raw, dark  and stronger  than  any  other  band.

As a result of years of hard work the members of the band decided to take apart for a while, thing that  was longer than a  little  while.   1994  will be the end of  the first part of this story.

1996 was the time to reborn, now the maturity, professionalism and perseverance would rule everything, a new lead guitar ( e. Zuñiga - who came from ‘’ atomic aggressor ‘’ )  gave the touch of technique that the band needed, so it began  again the way to get the time which had been lost. Now the band had changed its  lavel to ‘’ artaria recors’’ ( another chilean one ) ,  april, may  and june were the months  of arrangements , rehearsals and practices to carry out the second album,  the chosen name was ‘’ deadline sequences ‘’, 9 songs which reflected the new band step.

‘’deadline sequences ‘’ had a big promotion  playing  with cannibal corpse in Santiago in front of an audience about  7.000 persons,  it was a proud to chile the band’s performance.  Later came another shows with famous bands such as ; sodom, kreator  and broken hope.

A new member on bass ( j. E. Moore )  was the only change for the new record, the third one on  its  trajectory ,
‘’ a dwelling of gods ‘’ was the consolidation abroad, the lp is considered the more professional  and the best one.
This record includes eight songs, one of them the first cover that sadism has played ever, ‘’ beyond the gates ‘’  of  ‘’ possessed’’  ( one of the  biggest influence of the band ) .

Nowadays  sadism  is working on  its last production that will call  ‘’  s   u   m   m   o   n  ‘’,  with ten songs to the old death – metal style.   This work  will has a new member on guitar ( J. Menares ) ,  the old guitar player ( r. Salinas ) had to leave the band by personal problems.
