Question:
George Jacob Gershwin (; September 26, 1898 -  July 11, 1937) was an American composer and pianist. Gershwin's compositions spanned both popular and classical genres, and his most popular melodies are widely known. Among his best-known works are the orchestral compositions Rhapsody in Blue (1924) and An American in Paris (1928), as well as the contemporary opera Porgy and Bess (1935).
On September 26, 1898, George was born as second son to Morris and Rose Bruskin Gershwine in their second-floor apartment on Brooklyn's Snediker Avenue. His birth certificate identifies him as Jacob Gershwine, with the surname pronounced 'Gersh-vin' in the Russian and Yiddish immigrant community. He had just one given name, contrary to the American practice of giving children both a first and middle name. He was named after his grandfather, a one time Russian army mechanic. He soon became known as George, and changed the spelling of his surname to 'Gershwin' about the time he became a professional musician; other family members followed suit. After Ira and George, another boy Arthur Gershwin (1900-1981), and a girl Frances Gershwin (1906-1999) were born into the family.  The family lived in many different residences, as their father changed dwellings with each new enterprise in which he became involved. Mostly, they grew up around the Yiddish Theater District. George and Ira frequented the local Yiddish theaters, with George occasionally appearing onstage as an extra.  George lived a usual childhood existence for children of New York tenements: running around with his boyhood friends, roller skating and misbehaving in the streets. Remarkably, until 1908, he cared nothing for music, when as a ten year old he was intrigued upon hearing his friend Maxie Rosenzweig's, violin recital. The sound, and the way his friend played, captured him. At around the same time, George's parents had bought a piano, for lessons, for his older brother Ira, but to his parents' surprise, and Ira's relief, it was George who spent more time playing it.  Although his younger sister Frances was the first in the family to make a living through her musical talents, she married young and devoted herself to being a mother and housewife, thus surrendering any serious time to musical endeavors. Having given up her performing career, she settled upon painting as a creative outlet, which had also been a hobby George briefly pursued. Arthur Gershwin followed in the paths of George and Ira, also becoming a composer of songs, musicals, and short piano works.  With a degree of frustration, George tried various piano teachers for some two (circa. 1911) before finally being introduced to Charles Hambitzer by Jack Miller (circa. 1913), the pianist in the Beethoven Symphony Orchestra. Until his death in 1918, Hambitzer remained Gershwin's musical mentor and taught him conventional piano technique, introduced him to music of the European classical tradition, and encouraged him to attend orchestral concerts. Following such concerts, young Gershwin would essentially try to play, on the piano at home, the music he had heard from recall, and without sheet music. As a matter of course, Gershwin later studied with the classical composer Rubin Goldmark and avant-garde composer-theorist Henry Cowell, thus formalizing his classical music training.

Question:
Fear Factory is an American heavy metal band that was formed in 1989. Throughout the band's career, they have released nine full-length albums and have evolved through a succession of styles, including nu metal, death metal, groove metal, and thrash metal. Fear Factory was enormously influential on the heavy metal scene in the mid-to-late 1990s. Fear Factory went on hold in March 2002 following some internal disputes, but re-formed a year later without founding member Dino Cazares, adding bassist Byron Stroud, and previous bassist Christian Olde Wolbers as guitarist.
In 1991, Fear Factory recorded a series of cuts for their debut album with the then-little-known producer Ross Robinson in Blackie Lawless' studio. The band's members were unhappy with the terms of their recording contract and caused a delay with the album's release. The band retained the rights to the songs, many of which they re-recorded in 1992 with a different producer, Colin Richardson, for inclusion on their debut release Soul of a New Machine. Meanwhile, Ross Robinson obtained the rights to the recording, which he used to promote himself as a producer. The album was officially released in 2002 by Roadrunner Records under the title Concrete after the band's breakup. The release was controversial because the album was issued because of the band's outstanding contractual obligation and without the approval of every band member.  Fan opinion has been divided as to whether Ross Robinson's production properly captured the intricacies of the band's sound. The released album favored a straight-up approach and Robinson's distinct drum sound. Concrete has become an important album for fans of the early Fear Factory sound; it can be seen as a bridge between the band's sound on their demo recordings and their debut release, Soul of a New Machine, and a blueprint for later songs and B-sides.  Based on the Concrete recording, Max Cavalera recommended Fear Factory to the then-death-metal-focused Roadrunner Records label, which offered the band a recording contract. While the band signed the contract, it has since become controversial because of Roadrunner's treatment of the band during the events surrounding its 2002 breakup. This was reflected in the first album Archetype (2004), which was released following the band's re-formation. The opening song with lyrics by Burton C. Bell, "Slave Labor", was direct about the band's feelings on the matter. After working with numerous bassists, Andrew Shives was hired as a live bassist prior to the release of Soul of a New Machine.
