IN: 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.

OUT: 

input: In September 1970, Vaughan made his first studio recordings with the band Cast of Thousands, which included future actor Stephen Tobolowsky. They recorded two songs, "Red, White and Blue" and "I Heard a Voice Last Night", for a compilation album, A New Hi, that featured various teenage bands from Dallas. In late January 1971, feeling confined by playing pop hits with Liberation, Vaughan formed his own band, Blackbird. After growing tired of the Dallas music scene, he dropped out of school and moved with the band to Austin, Texas, which had more liberal and tolerant audiences. There, Vaughan initially took residence at the Rolling Hills Country Club, a venue that would later become the Soap Creek Saloon. Blackbird played at several clubs in Austin and opened shows for bands such as Sugarloaf, Wishbone Ash, and Zephyr, but could not maintain a consistent lineup. In early December 1972, Vaughan left Blackbird and joined a rock band named Krackerjack; he performed with them for less than three months.  In March 1973, Vaughan joined Marc Benno's band, the Nightcrawlers, after meeting Benno at a jam session years before. The band featured vocalist Doyle Bramhall, who met Vaughan when he was twelve years old. The next month, the Nightcrawlers recorded an album at Sunset Sound Recorders in Hollywood for A&M Records. While the album was rejected by A&M, it included Vaughan's first songwriting efforts, "Dirty Pool" and "Crawlin'". Soon afterward, he and the Nightcrawlers traveled back to Austin without Benno. In mid-1973, they signed a contract with Bill Ham, manager for ZZ Top, and played various gigs across the South, though many of them were disastrous. Ham left the band stranded in Mississippi without any way to make it back home and demanded reimbursement from Vaughan for equipment expenses; Ham was never reimbursed.  In 1975, Vaughan joined a six-piece band called Paul Ray and the Cobras that included guitarist Denny Freeman and saxophonist Joe Sublett. For the next two-and-a-half years, he earned a living performing weekly at a popular venue in town, the Soap Creek Saloon, and ultimately the newly opened Antone's, widely known as Austin's "home of the blues". In late 1976, Vaughan recorded a single with them, "Other Days" as the A-side and "Texas Clover" as the B-side. Playing guitar on both tracks, the single was released on February 7, 1977. In March, readers of the Austin Sun voted them as Band of the Year. In addition to playing with the Cobras, Vaughan jammed with many of his influences at Antone's, including Buddy Guy, Hubert Sumlin, Jimmy Rogers, Lightnin' Hopkins, and Albert King.  Vaughan toured with the Cobras during much of 1977, but near the end of September, after they decided to strive for a mainstream musical direction, he left the band and formed Triple Threat Revue, which included singer Lou Ann Barton, bassist W. C. Clark, and drummer Fredde Pharaoh. In January 1978, they recorded four songs in Austin, including Vaughan's composition "I'm Cryin'". The thirty-minute audio recording marks the only known studio recording of the band.
