Dream, formerly called DRM, is an all-female J-pop chorus group. In May 1999, the Japanese record company Avex Trax held a contest in the hopes of looking for new talent. After going through 120,000 Japanese contestants, Mai Matsumuro, Yu Hasebe and Kana Tachibana were chosen to form the new group "Dream". Many consider the first three girls as the first generation of Dream, which made its debut on January 1, 2000 with the single "Movin' on." Dream consisted of those three members until July 7, 2002 when Mai Matsumuro graduated to a solo career. Six new younger members joined the group (Risa Ai, Erie Abe, Aya Takamoto, Ami Nakashima, Shizuka Nishida and Sayaka Yamamoto) which allowed people to draw comparisons between the "new Dream" and another Japanese pop group, Morning Musume. Dream remained an 8-member dance & chorus group until the graduation of member Ai Risa on March 28, 2004. On June 25, 2007, the group decided it was time to have a makeover, and changed their name from Dream to DRM. The name reflects the change in the group itself, from a "young adolescence" image, to a "mature ladies" image. On July 22, 2008, it was announced that Yu Hasebe had left DRM, and that the group was changing its name to Dream. The remaining girls continued and in fall 2008 they worked together with the popular band EXILE. They recorded the song Love, Dream & Happiness along with the PV for EXILE's album, EXILE BALLAD BEST. After a longer absence on the release sector, Dream has finally announced the release of a new single titled Perfect Girls for September 2009.
