History
On October 10, 2013, in a post to her official Japanese blog, Riho Iida announced that she would be giving a concert on May 1, 2014, at the Nippon Budokan. Following that concert, she did not release any new music and instead began promoting her vocal tracks on Dubstep and Drum and Bass compilation albums. However, she did once again release a song in February 2015, named "愛の時間" ("Love Time") with remixes by Lex Sherwood, a popular EDM producer in the United States.

In October 2017, Riho Iida held a live event entitled Sōdanai Otona-ban, which was held to promote her upcoming album Sōdanai '99. At the event, she performed several songs from the album, as well as in collaboration with the most popular DJs of the late 90s (Manglitz, Verbal, David Ori and Slushii).

In March 2018, it was announced that Riho Iida would be releasing Sōdanai '99 in May 2018. Her first single for the album, titled "サイコBLACKOUT" (Gone), was released on April 10, 2018. A remix by Jeff Mills, featuring Riho Iida, was also released on the same day.

The second single, "SHINE SHINE LIGHT" (Bokura-dance)" was released on April 24, 2018. A 180 BPM tempo remix of the song, featuring Riho Iida, was released on May 3, 2018.

The album itself was released on May 3, 2018, and features the singles "shining light" (少年生), "Alone" (Hijō-shite), and "lonely night" (今池の夢).
