Ongaku Gatas (音楽ガッタス) was a Japanese pop girl group managed by UP-FRONT PROMOTION and formerly part of Hello! Project. The group was formed in 2007. The group's name combines the Japanese word "ongaku" (music) with the Portuguese word "gatas" (cats), taken from the name of the Hello! Project futsal team, Gatas Brilhantes. In early 2008, Erina Mano and Mika Muto (both Hello! Pro Eggs) graduated from the group. Mano left the group but continued as solo singer within Hello! Project Read more on Last.fm
