He was born in Tel Aviv in Israel in 1983 to parents Miki Kam, an actress, and Yehuda Eder, a musician.

His debut album, "Alon Eder", was released in February 2011 as a self-release and contained 15 songs that he composed, arranged and produced.

The album was preceded by the singles "A lot to say", "Don't leave me" and "Shir Lama", which was a success on radio stations.

In November 2018, Adar's seventh album, "Integrating in the Landscape", was released, which is the fourth created as part of the collaboration with the band.

In the same year, Eder and his partner Shani Gabai wrote the rock opera "Rubi Ge Behash".

In 2021, Eder collaborated with Jane Bordeaux again for a new single, Mashehu Tipshi (Cover of “Somethin' Stupid” by Frank & Nancy Sinatra).

In December 2021, another single was released with the participation of Chava Alberstein called "You have no right to pardon in the world", written by Leah Goldberg.

Mesika and Edar composed the song and it is the second single from a new concept album consisting entirely of Dayan's texts and letters.
