Background: Earth Crisis is an American metalcore band from Syracuse, New York, active from 1989 until 2001, reuniting in 2007. Since 1993 the band's longest serving members are vocalist Karl Buechner, guitarist Scott Crouse, bassist Ian Edwards and drummer Dennis Merrick. Their third guitarist Erick Edwards joined the band in 1998. The band has released eight studio albums, three compilations, two live albums and six music videos.
Context: The name of the band, Earth Crisis, indicates how their members see the current state of the planet and in their lyrics they seek to offer solutions to it; these are either "educational" or encourage direct-action. Most of them focus on rejection of recreational drugs, animal products, animal testing, industrial livestock production, illegal drug trade and an impending earth's doom caused by wars or an ecological collapse. On the other hand, they promote straight edge, veganism, self-empowerment and organizations such as Earth First!, Sea Shepherd Conservation Society and the Animal Liberation Front. In the words of the academic Jonathan Pieslak, some of their lyrics "read like passages" taken from "direct-action essays" of these institutions. Other subjects include criticism against white supremacy and, especially on Breed the Killers, oppressive governments. 2000's record Slither incorporated more topical issues, such as genetic engineering and second amendment rights. Their seventh and eighth albums, Neutralize the Threat and Salvation of Innocents, are concept albums entirely dedicated to real-life vigilantes and animal rights/anti-vivisection, respectively. The albums All Out War, Gomorrah's Season Ends and Breed the Killers included essays that delve into their lyrics and beliefs. According to the sociologist Ross Haenfler, Earth Crisis combined "youth crew's outspoken commitment to straight edge with Manliftingbanner's direct politics".  In a 1998 interview with Roadrunner Records, Karl Buechner described Earth Crisis' philosophy: "I want to boil it down to one notion: personal accountability. Respect for yourself, respect for the lives of innocent beings around us." He added that "Just being drug-free doesn't make you a good person, you need to use that clarity of the mind to become actively involved in the struggle that is being waged for earth, human and animal liberation." Their message disjoined from the "posicore" attitudes in its advocation for violent direct action. However, they believe that it must be used only as a last resort: "destruction and violence are the last thing I want to see but tragically, they are sometimes necessary. We place so far greater value on the lives of the innocent beings than any type of worth that could be put upon someone who's sadistic or greedy and doesn't want to change their profit system", said Buechner.  The band cited authors Peter Singer, John Robbins and Huey P. Newton as inspirations. In their live shows, there is usually literature about PETA, Greenpeace and others distributed. They have been longtime supporters for organizations such as the Animal Defense League, having done several benefit concerts for them. Nevertheless, they are not part of any of these groups or a political party: "We're about things we're interested in and we sing about things that happen politically, but we're not left-core or right wing. We don't want to get tangled up in someone else's agenda, which can happen if you join up in certain organizations."  Earth Crisis was occasionally misidentified with the hardline subculture, but they are not against homosexuality and believe that abortion should remain as an option in some instances. They also do not have a religious agenda and think that that is mainly a personal choice.

Problem: Background: The Birthday Party (originally known as The Boys Next Door) were an Australian post-punk band, active from 1978 to 1983. Despite limited commercial success, The Birthday Party's influence has been far-reaching, and they have been called "one of the darkest and most challenging post-punk groups to emerge in the early '80s." The group's "bleak and noisy soundscapes," which drew irreverently on blues, free jazz, and rockabilly, provided the setting for vocalist Nick Cave's disturbing tales of violence and perversion. Their music has been described by critic Simon Reynolds as gothic, and their single "Release the Bats" was particularly influential on the emerging gothic scene.
Context: The nucleus of the band first met at the private boys school Caulfield Grammar School, in suburban Melbourne, in the early seventies. A rock group was formed in 1973, with Nick Cave (vocals), Mick Harvey (guitar), and Phill Calvert (drums), with other students John Cocivera, Brett Purcell and Chris Coyne (on guitar, bass and saxophone respectively). Most were also members of the school choir. The band played under various names at parties and school functions with a mixed repertoire of David Bowie, Lou Reed, Roxy Music, Alice Cooper and the Sensational Alex Harvey Band, among others.  After their final school year in 1975 the band decided to continue as a four-piece group, with friend Tracy Pew picking up the bass. Greatly affected by the punk explosion of 1976 which saw Australian bands The Saints and Radio Birdman making their first recordings and tours, The Boys Next Door, as they were now called, began performing punk and proto-punk cover versions, such as "Blitzkrieg Bop" and "Gloria", and a few original songs. By November 1977 their set was dominated by fast original new wave material, such as "Sex Crimes" and "Masturbation Generation".  The Boys' second guitarist, Rowland S. Howard, joined in 1978, and about this time, the group's sound changed dramatically. The addition of Howard's guitar was certainly a catalyst (his later use of audio feedback being a hallmark of the group) but there were other changes, as well: their sound drew upon punk, rockabilly, free jazz and the rawest blues, but defied concise categorization. Many songs were driven by prominent, repetitive basslines and frenetic, yet minimalist, drumming. Though the band was tightly rehearsed, the instrumentalists often sounded as if they were on the verge of collapse, this quality only emphasising the newfound mania of Cave's singing, and his expressionist lyrics. In producer/engineer Tony Cohen they found a willing accomplice to their experimentation and their refusal to repeat themselves; and in manager Keith Glass they found an enthusiastic financial backer. Glass' label Missing Link Records released all of the early Birthday Party records.
