Perfume's show at the Tokyo Dome as part of their 10-year anniversary marked only the second time an all-female group had held a concert at the venue since SPEED. Tickets for the show were sold out on the day tickets were released. The demand for the tickets was so high that extra, unplanned seats were added. Perfume performed to 50,000 fans. At the end of the show, it was announced that Perfume would attend the Mnet Asian Music Awards (a Korean music-based award show that takes place in Macau), as one of the representatives for Japan alongside R&amp;B duo Chemistry. It was to be Perfume's first overseas performance. After the concert, a new single titled "Nee" was released on November 10, 2010, and like "Natural ni Koishite", it was a tie-up with Japanese apparel brand "Natural Beauty Basic". The single debuted at number 2 with first-week sales of 85,164, their highest first-week singles sales to date. On November 28, 2010, Perfume received the "Best Asia Artist Award" at the Mnet Asian Music Awards in Macau and later on performed "Nee" and "Chocolate Disco". The DVD of the "1 2 3 4 5 6 7 8 9 10 11" live performance at Tokyo Dome was released on February 9, 2011. Since February 2, 2011 a new song "Laser Beam" was featured in the adverts titled "Hyōketsu Dance" and "Hyōketsu Ice Music" for Kirin's chūhai drinks. Though it was announced on March 3, 2011 that their next single would be released on April 20, 2011, the official site announced on April 1, 2011, that the new single would be a double A-side single of "&lt;a href="Laser%20Beam/Kasuka%20na%20Kaori"&gt;Laser Beam/Kasuka na Kaori&lt;/a&gt;" and the release was suspended until May 5, 2011, due to the 2011 eastern Japan earthquake. The new release date of the single was then set to be on May 18, 2011.
