The Indigo is a Japanese band originally composed of Miki Taoka (田岡 美樹, Taoka Miki) on vocals, Yuichi Ichikawa (市川 裕一, Ichikawa Yūichi) on composition and arrangement, and Kenichi Takagi (高木 権一, Takagi Kenichi) on bass.
Their discography shows a gradual shift from an alternative-pop rock hybrid towards a preference for ballads.
This includes Namo Shirenu Hana (名も知れぬ花) for Ai Yori Aoshi, Under the Blue Sky for Someday's Dreamers, I Do!
They continued to release albums at a prodigious rate, averaging one per year, and toured Korea in late 2004 and early 2005.
They also made their first appearances in the United States at Otakon 2005 in Baltimore and Anime Expo 2006 in Los Angeles.
