Eufonius is a Japanese progressive pop rock music group which debuted on October 11, 2003 with the release of their first album Eufonius which was also an independent release. The band has produced songs for various anime and video games, such as Kashimashi: Girl Meets Girl, Himawari!, Noein, True Tears, Yosuga no Sora, Kokoro Connect, Shinkyoku Sōkai Polyphonica and visual novels like Key's Clannad and Favorite's Irotoridori no Sekai.

Internet radio showEdit

Eufonius hosts an Internet radio show called Frequency-e which had its first broadcast on May 30, 2005. The broadcasts are hosted by Riya and Hajime Kikuchi, and are available for download at Eufonius' official website.[3] Eufonius had originally planned to put out a new broadcast once a month, but due to being busy, they only release two or three a year in irregular intervals. As of December 17, 2011, there have been 12 broadcasts. The show primarily consists of Eufonius' members conversing, responding to listener's messages, or giving updates or general information on releases by the band. The name of the show comes from the name of the band's official website.
