Project "JaYammi" appeared in 2016 and at first it was a duet of colleagues from Transbaikalian scene Artem Praskov and Ivan Solomatov. The name of the band was born 15 minutes before the debut performance and meant "yummy Ja" (Ja is a Rastafarian god, yummy means "tasty" in American slang).
The band's repertoire includes such hits as "By the Fields", "Fog", "Sharpener" and others.
