Context paragraphs:
Failure (band): Failure is an American alternative rock band from Los Angeles that was active from 1990 to 1997 and from 2014 onwards.  They are often compared to other alternative rock bands from that time that were similarly labeled as "alternative", such as Nirvana and Soundgarden, but are distinguished by their meticulous attention to textural sonic detail, inventive use of guitar effects and signal processing, and the overall expansive sound design of their later albums.  Failure reunited in 2014.

Massacre (Argentine band): Massacre is an Argentine Alternative rock band, formed in 1986 in Buenos Aires.  It was formed by high school students influenced by American and British bands of the early 80s Alternative Rock movement.  Among his influences, artists like TSOL, Dead Kennedys, Black Flag, Nirvana, The Cure, Guns N' Roses, The Ramones, T. Rex, Sumo, Gustavo Cerati, Luis Alberto Spinetta, among others.  Taking cues from the Underground rock scene in the United States, they gained notoriety at the time for being an entirely independent group that self-managed its affairs, as well as producing and distributing its own records (attitudes which were still fairly foreign to Latin American rock bands of the era).  This helped pave way for the cult status that the band still enjoys within and outside their native Argentina.
