Concentration 20 is the third studio album by Japanese singer Namie Amuro. It was released on July 24, 1997, by Avex Trax. The album's musical style is a fusion of genres including pop, dance, rock, reggae and ska. Unlike Amuro's previous effort, Sweet 19 Blues (1996), which primarily had lyrics written by Tetsuya Komuro, Concentration 20's lyrics were mostly written by Marc Panther. Komuro did, however, compose and arrange most of the album's songs and wrote the lyrics to three of them. It was Amuro's second solo album since splitting up with Super Monkey's.

"A Walk in the Park" was released as the album's lead single on November 27, 1996. The single was very successful, becoming Amuro's fourth number one single on the Oricon Singles Chart and fourth million-seller. The second single, "Can You Celebrate?," was released on February 19, 1997. It became an unprecedented smash hit, selling over 2.29 million copies and remains the best-selling physical single by a female soloist in Japanese music history. "Can You Celebrate?" was certified double million by the Recording Industry Association of Japan (RIAJ), her first and last single to receive such a certification. The rock-infused third single, "How to Be a Girl," reached number one and sold over 770,000 copies, becoming Amuro's sixth number one single.

The album received positive reviews from music critics upon release, calling it more sophisticated than its predecessor. Concentration 20 was massively successful, premiering at the top of the Oricon Albums Chart with first-week sales of over 824,000 copies. It resided on the charts for 28 weeks, and was the seventh best-selling album of the year, selling nearly two million copies and is the 80th best-selling album of all time in Japan. Combined with the sales of its singles, Concentration 20 has sold around 4.5 million copies.

Background and recording

[edit]
The Record Plant (Hollywood, California) was one of the studios where the album was recorded.

In summer 1996, Amuro released her sophomore album Sweet 19 Blues, which was her first release since severing ties with Super Monkey's.[1] The album was a mammoth commercial success, reaching number one on the Oricon Albums Chart,[2] receiving a triple million certification from the RIAJ,[3] spawning three chart-toppers,[4][5][6] and was even the best-selling Japanese album of all time for a brief moment.[7] By the end of the year, Sweet 19 Blues was named the second best-selling album in Japan of 1996, trailing behind Globe's eponymous debut album.[8]

After this monumental success, recording for its follow-up began immediately. Much of the recording of Concentration 20 was done in the United States, primarily in California and New York.[9] Two weeks were devoted to recording in Santa Monica.[9] The title of the album was reportedly chosen because: "the studio at that time was on 20th Street in Santa Monica, and that is where we concentrated." Along with: "the 20th century is almost over, so let's concentrate on the time we have left," along with, "can we keep listening to this album throughout the 20th century?" The album was named so that it could be played with various meanings, such as "people who were 19 years old when Sweet 19 Blues was released are now entering their 20s," and so on, to broaden the imagination. Coincidentally, the title and Amuro's age at the time of release matched even though she was not aware of it.[10][11] Other well-known artists such as Marc Panther, Koji Kubo, and m.c.A.T (Akio Togashi) also participated in the production of the album.[9] "Storm" features m.c.A.T, as on the previous album.[9]

Composition

[edit]

The album concept was "Fancy & Cool," with the "glamorous and flashy" part emphasized in "Can You Celebrate?" and the "cool" part in "Close Your Eyes, Close To You," "Concentration 20 (Make You Alright)" and "Whisper."[11] The album embodies an array of styles including pop, rock and reggae.[12] Unlike her previous album, which was heavy on the pseudo-R&B side, Concentration 20 was practically void of it; therefore, the album took on a more electronic style similar to that of her producer's group, Globe.[12]

Opening the album is the industrial rock influenced track "Concentration 20 (Make You Alright)."[13] "B w/z you" is a mid-tempo number with a rock beat and a powerful hammering sound.[13] "Close Your Eyes, Close To You" is a Euro-style electronic rock tune with an intro that is prolonged and dynamic, leading the listener to believe it is an instrumental.[13] "Me Love Peace !!" is a reggae-style number with a ska beat that evokes the tropical mood of Okinawa.[13] She would not attempt a similar style again until 2005's "Want Me, Want Me," which featured prominent dancehall and reggaeton influences. "No Communication" is a dance pop number.[13] "A Walk In The Park" is a brisk electronic rock number with a chorus that envelops the listener in warm sunlight;[13] Komuro participates in the track by singing in the chorus.[13] "To-Day" is a mellow song with contemporary AOR influences.[13]

"Storm" is full-fledged rap number written by m.c.A.T. and composed by Akio Togashi.[9][13] "Whisper" is song that has a composition that changes from the whispering sound of the title to intense electronic rock.[13] "Can You Celebrate?" is a power ballad with a gospel-like chorus, a string orchestra and a piano sound.[13] "I Know…" is an instrumental with an electric sound.[13] "How to be a Girl" is an upbeat dance rock number.[13]

Singles and other songs

[edit]

The singles from this album were very successful, two were million sellers and all three reached the top spot of the Oricon Singles Chart.

"A Walk in the Park" was released as the album's lead single on November 27, 1996, four months after the massive success of Sweet 19 Blues.[14] It became her fourth number one and million selling single.[15][16] The single spent seven weeks into the top five and eight weeks in top ten totally.[17][18][19][20][21][22] "A Walk in the Park" was the thirteenth best-selling single of the year 1997 in Japan.[23] It was certified million in January 1997.[16] "A Walk in the Park" ranks as her fifth best-selling single in the country.[24]

February 19, 1997, saw the release of the album's second single, "Can You Celebrate?."[25] Amuro began the year 1997 with her defining single and biggest success to date.[24] It opened at the top spot on the singles chart with over 800,000 copies sold in its first week,[26] the highest first week sales for any of Amuro's singles and the eighth highest opening sales of all time for a CD single in Japan.[27] It spent two consecutive weeks at number one,[26][28] seven weeks in the top five and eight weeks in top ten totally.[29][30][31][32][33][34] It charted for fourty weeks.[35] "Can You Celebrate?" was the biggest-selling single of 1997,[23] and is the fourteenth best-selling single in Japanese music history,[36] with sales of over 2.29 million copies.[37] It also received a double million certification from the Recording Industry Association of Japan (RIAJ) in March 1997, making it her only single to accomplish this.[38] A maxi-single reissue of "Can You Celebrate?" was released on Christmas Day 1997 to commemorate Amuro's nuptial with Masaharu "Sam" Maruyama and was also successful with about 500,000 units sold, while also being certified platinum in January 1998.[39] In December 1997, the song helped her to win the Best Single Award at the 39th Japan Record Awards.[40]

"How to Be a Girl" is the third and last single from the album and was released on May 21, 1997.[41] "How to Be a Girl" is Amuro's first attempt at rock music. The single still managed to be a commercial success, spending two consecutive weeks at number one and selling over 770,000 copies, included over 300,000 copies purchased in its opening week.[42] "How to Be a Girl" was also the 23rd best-selling single of 1997.[23] In June 1997, the single was certified million.[43] "How to Be a Girl" is Amuro's seventh best-selling single overall.[24]

Tie-ups and theme songs

[edit]

"A Walk in the Park" and "Can You Celebrate?" were both jingles for Maxell UD commercials and "Whisper" was used as the background music for the Maxell MD74 commercial.[44] "Can You Celebrate?" was also the theme song of the dorama Virgin Road.[45] "How to Be a Girl" was used as background music in four commercials for Sea Breeze products. The first commercial was promoting a sun lotion, the second a shampoo, the third a deodorant and the last a moisturizer.[46] "No Communication" was used as background music in a commercial for the DyDo Mistio drinks.[47]
