angela is a JPop duo from Okayama, Japan composed of atsuko (lyrics, vocals, musical composition) and KATSU (musical composition and arrangment, keyboards, guitar).

angela has released a grand total of nineteen singles (six on a major label), one maxi single, one promotional CD, four mini CD albums, and five full-length CD albums (one on a major label). Additionally, their music has been featured on other anime-related soundtrack CDs.

Ironically, atsuko and KATSU did not realize that they were both born in the same town of Okayama until they went to the same music school in Tokyo. There, their same origin allowed them to bond together into the earliest incarnation of angela. They decided to work together, and they have come a long way since then.

Originally, angela was an independent band, performing in clubs and otherwise since 1993 and in 1999 they made their debut with the single memories, however this release went largely unnoticed. In 2002, they were signed by KING RECORDS after one of their representatives heard a song that Katsu had improvised from the ever-popular Zankoku na Tenshi no Thesis. After that, their debut single, Asu e no brilliant road became the cornerstone of success for angela. This was success that granted them several popular singles for the Uchuu no Stellvia and Sokyuu no Fafner anime series and a popular album, Sora no Koe — success that granted them even a live concert in the United States at Otakon 2004 in Baltimore, Maryland. .
