БУТ became a band in the spring of 2009 by the drummer Zbyňa (ex-member of a Czech grind core band Ingrowing) and the guitarist Honza (ex-member of a Czech grind core band Uprise). Soon after that the bassist, Kenny (ex-member of a metal crust band Den Za Dnem), joined the two. After that the microphone got into the hands of S.I.D. (ex-member of a hard core band Scrab Plastic, R.I.P.). In July of 2009 they recorded their first seven-track demo recording promo material in the Hellsound studio and they played their first live shows.
