Answer by taking a quote from the following article:

Troyal Garth Brooks (born February 7, 1962) is an American singer and songwriter. His integration of rock and roll elements into the country genre has earned him immense popularity in the United States. Brooks has had great success on the country single and album charts, with multi-platinum recordings and record-breaking live performances, while also crossing over into the mainstream pop arena. According to the RIAA, he is the best-selling solo albums artist in the United States with 148 million domestic units sold, ahead of Elvis Presley, and is second only to the Beatles in total album sales overall.

Brooks' third album, Ropin' the Wind, was released in September 1991. It had advance orders of 4 million copies and entered the Billboard 200 at No. 1, a first for a country artist. The album's musical content was a melange of pop country and honky tonk; singles included "The River", "What She's Doing Now", and a cover of Billy Joel's "Shameless". It would become Brooks' second-best selling album, after No Fences. The success of Ropin' the Wind further propelled the sales of Brooks' first two albums, enabling Brooks to become the first country artist with three albums listed in the Billboard 200's top 20 in one week.  After spending time in Los Angeles during the 1992 riots, Brooks co-wrote a gospel-country-rock hybrid single, "We Shall Be Free", to express his desire for tolerance. The song became the first single off his fourth album The Chase. The album only reached No. 12 on the Billboard Top Country Albums chart, Brooks' first song in three years to fail to make the top 10. Nonetheless, "We Shall Be Free" peaked at No. 22 on the Billboard Christian Songs charts through a marketing deal with Rick Hendrix Company, and earned Brooks a 1993 GLAAD Media Award. The next single released from The Chase was "Somewhere Other Than the Night", followed by "Learning to Live Again", which peaked at numbers one and two on the Hot Country Songs chart, respectively. The album's final single, "That Summer", would go on to be the most successful single from the album, reaching No. 1 in July 1993.  Brooks released his first Christmas album, "Beyond the Season" on August 25, 1992. The album included classics such as "White Christmas" and "Silent Night" as well as an original tune "The Old Man's Back in Town." "Beyond the Season" was the best selling Christmas album in 1992, peaking at No. 2 on the Billboard 200 chart.  In 1993, Brooks, who had criticized music stores selling used CDs since it led to a loss in proper royalty payments, persuaded Capitol Records to not ship his 1993 album, In Pieces, to stores which engaged in this practice. This led to several anti-trust lawsuits against the record label, ending with Capitol shipping the albums to the stores anyway.  Despite the delay in shipping, In Pieces was another success, peaking at No. 1 on both the Billboard 200 and Top Country Albums charts, and selling a total of nearly 10 million copies. After a delay in its worldwide release, the album also peaked at No. 2 on the United Kingdom Albums Chart. That same year, "The Red Strokes" became Brooks' first single to make the UK Singles Chart, reaching a high of No. 13; it was followed by "Standing Outside the Fire", which reached No. 23. Previous albums No Fences, Ropin' the Wind and The Chase also remained in the top 30 in the UK Albums Chart.  Brooks' first world tour began in 1993, reaching the UK after many domestic concerts. Brooks sold out venues such as Birmingham's National Exhibition Centre and London's Wembley Arena, a feat never accomplished by an American country music artist. He also began the London radio station, Country 1035. Despite the disdain of the British media, Brooks' overall popularity in the country was evident, with a top disc jockey, Nick Barraclough, referring to Brooks as Garth Vader (a play on Darth Vader) for his "invasion" of the charts and his success in the country genre. Unlike Alan Jackson, who refused to return to the UK after being treated in a similar negative manner by the press, Brooks would later return in 1996 for more performances. Brooks also took is World Tour to other regions throughout Europe, as well as Brazil, the Far East, Australia, and New Zealand.  In 1994, Brooks paid homage to one of his musical influences, Kiss, appearing on the tribute compilation, Kiss My Ass: Classic Kiss Regrooved, a collection of songs performed by popular artists from various genres. The unlikely collaboration of Brooks and Kiss' rendition of "Hard Luck Woman" was performed live on The Tonight Show with Jay Leno, and despite its hard-rock appeal, Brooks' version appeared on the Billboard Hot Country Songs chart.  In 1999, Brooks took on the alter ego of "Chris Gaines", a fictitious rock and roll musician and character for an upcoming film, The Lamb. In October 1999, the films pre-release soundtrack, Garth Brooks in ... The Life of Chris Gaines (also dubbed Gaines' Greatest Hits), was released to much public criticism. Brooks also appeared as Gaines in a television mockumentary for the VH1 series Behind the Music, and as the musical guest on an episode of Saturday Night Live, which he also hosted as himself.  Brooks' promotion of the album and the film did not promote excitement and the failure of the Gaines project evident mere weeks after the album was released. The majority of the American public was either bewildered, or completely unreceptive to the idea of Brooks portraying a rock and roll musician. Sales of the album were unspectacular, at least compared with most of Brooks' previous albums, and although it made it to No. 2 on the Billboard 200 chart, expectations had been higher and retail stores began heavily discounting their oversupply. Less-than-expected sales of the album (more than two million) brought the project to an indefinite hiatus in February 2001 and Gaines quickly faded into obscurity.  Despite the less-than-spectacular response to the Gaines project, Brooks gained his first (and only) Billboard Top 40 pop single in "Lost in You". The album was later certified Double Platinum by the RIAA.  On November 23, 1999, Brooks released his second holiday album, Garth Brooks and the Magic of Christmas. The album peaked at No. 7 on Billboard's Top 200 and No. 1 on the Top Country Albums, making it Brooks' 10th number-one album.
