Tsunku, the producer of Hello!Project, announced in June 2006 that he would create a unit consisting of Aya Matsuura and Fujimoto Miki.
A side-project was nothing new for the two girls who had been in various projects before, teaming up with other members from Hello!Project. It also wasn't the first time that they worked together: they had both been in the group Gomattou, which had only released one single. Tsunku ensured pretty quickly that this wouldn’t be a temporal project; instead it was going to be a solid unit.
Their first single, Thanks, was released in September. It immediately turned out to be very successful as it entered the Oricon charts at rank two. The single was used as the main theme for the movie "Sukeban Deka IV", starring Aya Matsuura as well.
Melodies followed in October and was a success as well. However, the music video of Melodies caused quite some tumult in Japan because it ended with the two girls kissing. A censored version was released as well, and instead of airing the whole video, the video comes abruptly to an end just before the kiss scene.
The duo released two more singles in March 2007, one of them being the limited release Daisuki Rakuten Eagles, which was a cheer song for the baseball team Tohoku Rakuten Golden Eagles. As a limited release, it was only available for purchase on the Rakuten Golden Eagles' website. A few months later, the duo released their first album, 1st GAM ~Amai Yûwaku~ in May. In August, their first live DVD was released.
Although the group was originally announced as a solid unit, after 2007 there was very little heard from GAM. As Fujimoto Miki and Matsuura Aya both graduated from Hello!Project in March 2009, it seems unlikely that the unit will reappear in Japan's showbiz world again.
