The band was formed in 2006, but began gaining actual recognition in early 2007. In September 2007, AdaKaiN released their first EPTears of Dysphoria. The symbolic reference to the title of the EP refers to their outlook on not only what has happened to the music industry today, but also the chaotic surrealism that plagues the minds of society. The E.P. was recorded with award winning and well-established producer Eric Delegard.
AdaKaiN's debut full-length, Together in the Heart was recorded in July, with Delegard once again behind the mixing board, and self-released on October 31. For this album the quintet started with the blueprint established on Tears of Dysphoriap/i] but this time delved deeper emotionally and musically.
