Some context: Testament is an American thrash metal band from Berkeley, California. Formed in 1983 under the name Legacy, the band's current lineup comprises guitarists Eric Peterson and Alex Skolnick, lead vocalist Chuck Billy, drummer Gene Hoglan, and bassist Steve Di Giorgio. Since its inception, Testament has had numerous lineup changes, leaving Peterson as the only constant member. Billy replaced original singer Steve "Zetro" Souza (who left the band to join Exodus as the replacement of Paul Baloff) in 1986, prior to the recording of their first studio album, The Legacy, and has been a member of the band since.
As early as 2009, Testament commenced writing new material for their tenth album. In an interview with Metalheadz, guitarist Eric Peterson stated that there were about four songs written and that "there's other guys in the band who like to play the more rock melodic style but the next one is gonna be a bit heavier." In a January 2011 interview during the 70000 Tons of Metal cruise, frontman Chuck Billy revealed that Testament had been working on six new songs, with four or five "maybe left to write," and would begin recording their new album by early March. On 18 May 2011, guitarist Alex Skolnick posted an update on his Twitter, saying, "Another tune done! My riffs from last week [plus] some of [fellow Testament guitarist Eric Peterson's plus] new ones we wrote today. Planning one more, then we've got more than we need."  Testament began recording their tenth studio album on June 20, 2011. Drummer Paul Bostaph was unable to take part in the recording due to a "serious injury", although he was expected to rejoin when the band tours to support the album. Gene Hoglan, who played drums on the band's 1997 album Demonic, filled in for Bostaph. It was also reported that Lamb of God drummer Chris Adler would make a special guest appearance on a couple of bonus tracks.  Testament appeared at the California dates of the summer 2011 Rockstar Energy Drink Mayhem Festival, replacing In Flames.  On 14 July 2011, it was announced that the tenth Testament studio album would be called Dark Roots of Earth, which, after many delays, was released on July 27, 2012. Dark Roots of Earth debuted at No. 12 on Billboard 200, the band's highest chart position to date. Prior to the album's release, the band toured in the fall of 2011 with Anthrax and Death Angel. Overkill was invited to the tour, but due to the pre-production of their sixteenth studio album The Electric Age, they did not participate. It was announced on 1 December 2011 that Paul Bostaph had left Testament. Gene Hoglan recorded the drum tracks for Dark Roots of Earth and continues to play live with the band. In interviews, Testament have expressed pleasure in Hoglan's playing, and hope that he would continue playing with the band for the foreseeable future.

Some context: The French (French: Francais) are an ethnic group and nation who are identified with the country of France. This connection may be legal, historical, or cultural. Historically the French people's heritage is diverse, including populations of Gauls, Ligures, Latins, Franks, Iberians, Alamans and Norsemen. France has long been a patchwork of local customs and regional differences, and while most French people still speak the French language as their mother tongue, languages like Norman, Occitan, Catalan, Auvergnat, Corsican, Basque, French Flemish, Lorraine Franconian, Alsatian and Breton remain spoken in their respective regions.
With the decline of the Roman Empire in Western Europe, a federation of Germanic peoples entered the picture: the Franks, from which the word "French" derives. The Franks were Germanic pagans who began to settle in northern Gaul as laeti, already during the Roman era. They continued to filter across the Rhine River from present-day Netherlands and Germany between the third to the 7th century. At the beginning, they served in the Roman army and reached high commands. Their language is still spoken as a kind of Dutch (Flemish - Low Frankish) in northern France (Westhoek) and Frankish (Central Franconian) in German speaking Lorraine. Another Germanic people immigrated massively to Alsace: the Alamans, which explains the Alemannic German spoken there. They were competitors of the Franks; that's why, in Renaissance times, it became the French word for "German": Allemand.  By the early 6th century the Franks, led by the Merovingian king Clovis I and his sons, had consolidated their hold on much of modern-day France, the country to which they gave their name. The other major Germanic people to arrive in France (after the Burgundians and the Visigoths) were the Norsemen or Northmen, (which was shortened to Norman in France), Viking raiders from modern Denmark and Norway, who settled with Anglo-Scandinavians and Anglo-Saxons from the Danelaw definitely in the northern region known today as Normandy in the 9th and 10th century, and which was given in fiefdom of the kingdom of France by king Charles III. The Vikings eventually intermarried with the local people, converting to Christianity in the process. It was the Normans who, two centuries later, would go on to conquer England and Southern Italy.  Eventually, though, the largely autonomous duchy of Normandy was incorporated back into the royal domain (i. e. the territory under direct control of the French king) in the Middle Ages. In the crusader Kingdom of Jerusalem, founded in 1099, at most 120 000 Franks (predominantly French-speaking Western Christians) ruled over 350,000 Muslims, Jews, and native Eastern Christians.
