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.
Although ideologically tied to the straight edge movement, the initial musical influences of Earth Crisis were mainly from New York hardcore bands such as Agnostic Front, Cro-Mags and Sick Of It All. After the All Out War EP, they developed an increasingly technical and heavier style, citing death metal bands Napalm Death, Bolt Thrower and Obituary as prime inspirations. Buechner's vocals became rougher with each release as well, culminating in the completely gutturally screamed Gomorrah's Season Ends. Terrorizer magazine referred to this album as "heavy hardcore taken to a new level, all the blackness that was hinted at on Firestorm realized in all its formidable glory." In this period, many of their songs were built on Merrick's drum beats.  Their third studio album, Breed the Killers, maintained the previous aggressiveness and its growled vocals were "taken about as far as possible", but it followed a structure more akin to the "post-Judge hardcore of the Path of Resistance record Who Dares Wins", according to Shawn Macomber of Decibel. Dennis Merrick said: "On Breed the Killers I think we achieved the most honest representation of our sound without sounding too raw or too slick". Its follow-up, Slither, had a change of style that steered towards nu metal. Buechner declared that, rather than being influenced by other styles, they "resurrected" the sound of All Out War in a proper way, which also had melodic choruses and spoken word verses.  Their first post-reunion album, To the Death, was described by Buechner as "a mixture between Destroying the Machines and Breed the Killers." According to Stereo Killer, it was "arguably the band's heaviest offering" but with "more traditional verse/chorus/verse" material. Neutralize the Threat followed a similar path, but "with a Gomorrah's Season Ends vibe thrown in", the band stated. Scott Crouse said that he always tried "to get the perfect blend of heaviness, imagery and listenability" and that these two albums were the first to "hit that mark". Salvation of Innocents included, in addition, some clean vocals that were compared by one reviewer to the sludge metal band Crowbar, as well as "some elements of European melodic metalcore" and faster songs.  When asked what ten bands inspired Earth Crisis over the years in a 2016 interview, Scott Crouse named DYS, Judge, Corrosion of Conformity, Agnostic Front, Slayer, Sepultura, Metallica, Conviction, Zero Tolerance and Iron Maiden.

what were the titles of their releases?

Answer the question at the end by quoting:

Curtis Mayfield was born on June 3, 1942 in Chicago, Illinois, the son of Marion Washington and Kenneth Mayfield, one of five children. Mayfield's father left the family when Curtis was five; his mother (and maternal grandmother) moved the family into several Chicago public housing projects before settling in Cabrini-Green during his teen years. Mayfield attended Wells Community Academy High School before dropping out his sophomore year. His mother taught him piano and, along with his grandmother, encouraged him to enjoy gospel music.
Curtis Mayfield was known for introducing social consciousness into African-American music. Having been raised in the Cabrini-Green projects of Chicago, he witnessed many of the tragedies of the urban ghetto first hand, and was quoted saying "With everything I saw on the streets as a young black kid, it wasn't hard during the later fifties and sixties for me to write my heartfelt way of how I visualized things, how I thought things ought to be."  Following the passing of the Civil Rights Act of 1964, his group the Impressions produced music that became the soundtrack to a summer of revolution. It is even said that "Keep On Pushing" became the number one sing along during the Freedom Rides. Black students sang their songs as they marched to jail or protested outside their universities, while King often used "Keep On Pushing", "People Get Ready" and "We're A Winner" because of their ability to motivate and inspire marchers. Mayfield had quickly become a civil rights hero with his ability to inspire hope and courage.  Mayfield was unique in his ability to fuse relevant social commentary with melodies and lyrics that instilled a hopefulness for a better future in his listeners. He wrote and recorded the soundtrack to the 1972 blaxploitation film Super Fly with the help of producer Johnny Pate. The soundtrack for Super Fly is regarded as an all-time great body of work that captured the essence of life in the ghetto while criticizing the tendency of young people to glorify the "glamorous" lifestyles of drug dealers and pimps, and illuminating the dark realities of drugs, addiction, and exploitation. His work influenced many, and it is said that Mayfield truly introduced a new style of black music.  Mayfield, along with several other soul and funk musicians, spread messages of hope in the face of oppression, pride in being a member of the black race and gave courage to a generation of people who were demanding their human rights, without abandoning the struggle for equality. He has been compared to Martin Luther King, Jr. for making a lasting impact in the civil rights struggle with his inspirational music. By the end of the decade Mayfield was a pioneering voice in the black pride movement, along with James Brown and Sly Stone. Paving the way for a future generation of rebel thinkers, Mayfield paid the price, artistically and commercially, for his politically charged music. Mayfield's "Keep On Pushing" was actually banned from several radio stations when riots began flaring up in some cities. Regardless of the persistent radio bans and loss of revenue, he continued his quest for equality right until his death. His lyrics on racial injustice, poverty and drugs became the poetry of a generation.  Mayfield was also a descriptive social commentator. As the influx of drugs ravaged through black America in the late 1960s and 1970s his bittersweet descriptions of the ghetto would serve as warnings to the impressionable. "Freddie's Dead" is a graphic tale of street life, while "Pusherman" revealed the role of drug dealers in the urban ghettos.

Was the ban eliminated later on?
