Dream (ドリーム, Dorīmu) was a Japanese pop girl group. The group was formed as a result of a 1999 talent contest called "Avex Dream 2000". Originally a three-piece group consisting of Mai Matsumuro, Kana Tachibana, and Yu Hasebe, the group has undergone many changes since its debut in 2000 on the Avex Trax label, and none of the original trio remain. The original trio sold over 950,700 records, and in total the group has sold over 1,100,000 records over the span of 10 years. On July 7, 2002, following the departure of Mai Matsumuro, the lineup of the group changed frequently over the years. At one point, the group had become an 8-member ensemble. Eventually in 2017, the group announced their official disbandment due all members leaving to pursue on their own activities. (From Wikipedia, the free encyclopedia)
