input: Federer entered the top 100 ranking for the first time on 20 September 1999 and started at the 1999 Marseille Open defeating the reigning champion of the 1998 French Open, Spaniard Carlos Moya. His first final came at the Marseille Open in 2000, where he lost to fellow Swiss Marc Rosset. Federer won the 2001 Hopman Cup representing Switzerland, along with Martina Hingis. The duo defeated the American pair of Monica Seles and Jan-Michael Gambill in the finals. Federer would later say that his experience with Hingis "definitely helped me to become the player I am today." Federer's first singles win was at the 2001 Milan Indoor tournament, where he defeated Julien Boutter in the final. Although he won his first title already in 1999 on the Challenger tour, winning the doubles event in Segovia, Spain with Dutchman Sander Groen, the final was played on Federer's 18th birthday. In 2001, Federer made his first Grand Slam quarterfinal at the French Open, losing to former world No. 2 and eventual finalist Alex Corretja. His run to the French quarterfinals launched him into the top 15 for the first time in his career. His international breakthrough came at the 2001 Wimbledon Championships, where a 19-year-old Federer faced the four-time defending champion and all-time Grand Slam leader Pete Sampras. The teenage Swiss stunned the seven-time Wimbledon champion and No. 1 seed in a dramatic five-set epic to reach the quarterfinals. In the quarters he faced Englishman Tim Henman, eventually losing in an overtime fourth-set tiebreaker. Federer's breakthrough at Wimbledon signaled the record-breaking dominance he would display at the All England Club over the next two decades. The first final he reached at the prestigious Masters level came at the 2002 Miami Masters event, where he lost to former and future world No. 1 Andre Agassi on hard court. Federer won his first Master Series event at the 2002 Hamburg Masters on clay, over Marat Safin; the victory put him in top 10 for the first time. Federer made 10 singles finals between 1998 and 2002, of which he won four and lost six. He also made six finals in doubles. Of note are Federer and partner Max Mirnyi's defeat in the final of the Indian Wells Masters in 2002, and their victory in the same year in the final of the Rotterdam 500 series event. Federer had won the latter a year earlier with partner Jonas Bjorkman. He finished 2001 with an ATP ranking of No. 13, and 2002 was the first year he was ranked within the top 10, finishing at No. 6.

input: The ancient peoples now called "Celts" spoke a group of languages that had a common origin in the Indo-European language known as Common Celtic or Proto-Celtic. This shared linguistic origin was once widely accepted by scholars to indicate peoples with a common genetic origin in southwest Europe, who had spread their culture by emigration and invasion. Archaeologists identified various cultural traits of these peoples, including styles of art, and traced the culture to the earlier Hallstatt culture and La Tene culture. More recent genetic studies have indicated that various Celtic groups do not all have shared ancestry, and have suggested a diffusion and spread of the culture without necessarily involving significant movement of peoples. The extent to which "Celtic" language, culture and genetics coincided and interacted during prehistoric periods remains very uncertain and controversial. Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages. The term "Celt" was used in classical times as a synonym for the Gauls (Keltoi, Celtae). Its English form is modern, attested from 1607. In the late 17th century the work of scholars such as Edward Lhuyd brought academic attention to the historic links between Gaulish and the Brythonic--and Goidelic--speaking peoples, from which point the term was applied not just to continental Celts but those in Britain and Ireland. Then in the 18th century the interest in "primitivism", which led to the idea of the "noble savage", brought a wave of enthusiasm for all things Celtic and Druidic. The "Irish revival" came after the Catholic Emancipation Act of 1829 as a conscious attempt to demonstrate an Irish national identity, and with its counterpart in other countries subsequently became the "Celtic Revival".

input: In late 2014, the band went on another hiatus. Aaron Lewis continued to play solo shows and work on his next solo album. He also confirmed that the hiatus would last "for a while". Mike Mushok teamed up with former Three Days Grace singer Adam Gontier, former Finger Eleven drummer Rich Beddoe and Eye Empire bassist Corey Lowery to form Saint Asonia. When asked in an August 2016 interview about Staind's future, Mushok stated that the hiatus could possibly be the end of the band. He explained, "I remember '09, we stopped touring, and we did a record after that. We did the self-titled Staind record, which we did a little touring on. It was one of my favorite Staind records we had done. Aaron, I know, has another country record coming out in September. So...you know, we say we're gonna do something else, but there's no real plan for it right now. I know he's pursuing. And I know we're writing another record.". In addition, Aaron Lewis indicated that he is focused on country music while noting "Do I think there's room somewhere down the road for Staind to play shows in the summertime, radio festivals and stuff like that? Sure. Do I think I have another one of those Staind records in me? Of course I do. All I have to do is live." On August 4, 2017, the band performed for the first time since November 2014 for an acoustic performance at Aaron Lewis' 6th annual charity golf tournament and concert when bassist Johnny April & drummer Sal Giancarelli joined Aaron Lewis & Mike Mushok to perform "Outside", "Something to Remind You", and "It's Been Awhile". Three days later, Lewis announced that Staind would never tour extensively again, stating: The touring machine, as you call it, of Staind will never be again. Not like that, no. Never. I could never go back to playing six shows [a week] eight weeks in a row. I can't do that. I have grown in my age and become very accustomed to playing Thursday, Friday and Saturday and being able to go home for a few days and unwind and try to kind of have a life aside from doing this.
