Document 2: Seattle's Best Coffee: In 1983, the name again changed from Stewart Brothers Wet Whisker to Stewart Brothers Coffee. Shortly after, business began to expand, and new shops opened in Bellevue, Washington, and in Seattle's historic Pike Place Market a year later. In 1991, the company was renamed "Seattle's Best Coffee" after winning a local competition. Around 1995, Seattle's Best Coffee was purchased by a group of investors who own Torrefazione Italia. They formed a new company made up of both parties called Seattle Coffee Holdings. In 1997, Seattle Coffee Holdings changed its name to Seattle Coffee Company.
Document 3: Demon Hunter: Demon Hunter is an American Christian metal band from Seattle, Washington, started in 2000 by brothers Don Clark and Ryan Clark. Although the brothers created the band together, only Ryan remains, since Don left the band to take care of his family. As of early 2010, the band has sold over half a million albums. The band's style is known for combining nu metal sounds and qualities with ones heard in metalcore.
Document 4: Hard rock: Although Foo Fighters continued to be one of the most successful rock acts, with albums like In Your Honor (2005) reaching number two in the US and UK, many of the first wave of post-grunge bands began to fade in popularity. Acts like Creed, Staind, Puddle of Mudd and Nickelback took the genre into the 2000s with considerable commercial success, abandoning most of the angst and anger of the original movement for more conventional anthems, narratives and romantic songs. They were followed in this vein by new acts including Shinedown and Seether. Acts with more conventional hard rock sounds included Andrew W.K., Beautiful Creatures and Buckcherry, whose breakthrough album 15 (2006) went platinum and spawned the single "Sorry" (2007), which made the Top 10 of the Billboard 100. These were joined by bands with hard rock leanings that emerged in the mid-2000s from the garage rock or post punk revival, including Black Rebel Motorcycle Club and Kings of Leon, and Queens of the Stone Age from the US, Three Days Grace from Canada, Jet from Australia and The Datsuns from New Zealand. In 2009 Them Crooked Vultures, a supergroup that brought together Foo Fighters' Dave Grohl, Queens of the Stone Age's Josh Homme and Led Zeppelin bass player John Paul Jones attracted attention as a live act and released a self-titled debut album that reached the top 20 in the US and UK and the top ten in several other countries.
Document 5: Avenged Sevenfold: Before the release of their debut album, the band recorded two demos in 1999 and 2000. In mid-2001, it was reported that Meacham had attempted suicide by drinking excessive amounts of cough syrup. The attempt affected the band's Take Action Tour. During his hospitalization he remained in poor condition and was replaced by Dameon Ash. In an interview, lead singer M. Shadows said of Meacham that ``he perma - fried his brain and was in a mental institution for a long time, and when you have someone in your band who does that, it ruins everything that's going on all around you, and it makes you want to do something to prevent it from happening to other people. ''Avenged Sevenfold's debut album, Sounding the Seventh Trumpet, was recorded when the band members were in their late teens and still in high school. It was originally released on their first label, Good Life Recordings in 2001. When lead guitarist Synyster Gates joined the band after the album was released, the introductory track`` To End the Rapture'' was re-recorded featuring a full band element. The album was subsequently re-released on Hopeless Records in 2002. The band started to receive recognition, performing with bands such as Mushroomhead and Shadows Fall and playing on the Take Action Tour.
Document 6: Metallica: This Monster Lives: The book follows the emotional roller-coaster both he and his film partner Bruce Sinofsky and the band Metallica went through during the creation film. The book takes in the time from Berlinger and Sinofsky's first meeting with Metallica in 1999 to the 2003 Summer Sanitarium Tour. Berlinger and Sinofsky's relationship was at an all time low, exacerbated by Berlinger's decision to direct the disastrous sequel to the Blair Witch. At the start of filming the relationship between the band members, especially between vocalist James Hetfield and drummer Lars Ulrich, is in a similarly perilous position after bassist Jason Newsted quit the band and long standing grudges between the remaining members threaten to escalate past the point of no return.
