Ra'ash released their debut album Noise Only Noise. N. (רעש רק רעש. ק.) in 1994 to critical acclaim. Kertes wrote and sang most of the songs on the album, although the songs that were written and sung by the second singer Jonnie Shualy gained more popularity.
In 1995 Kertes and all of the members of Ra'ash participated in recording of Shualy's first solo album The Thousand and One (האלף ואחד).
In 1996 Ra'ash released their second album, "Tmimot" (תמימות) . All of the album was written and sung by Kertes.

In the same year Kertes played in an album by the popular Israeli singer Yael Levi, which Shualy produced.
In 2000 Ra'ash released their last album as a band, Ani Ze Lo' Ata (אני זה לא אתה). Singing and songwriting on this record were roughly divided between Kertes and Shualy. The album received positive reviews, but the band went on an indefinite hiatus shortly after its release.
In 2001 Ra'ash played their last show as a band at a two-day festival of Nana Disc artists.
In 2003 Kertes released his first solo album, Yellow Sea (ים צהוב).
