SinHeresY rose officially in May 2009 in Trieste when the bassist Davide Sportiello met the guitarist Lorenzo Pasutto and the Friulian singer Cecilia Petrini. In the following months, the drummer Alex Vescovi and the vocalist Stefano Sain joined the band. With this line-up, SinHeresY started in May 2010 their live activity in Friuli and in the near-by Slovenia and in September the band realized a home-made demo containing two original songs with power metal influences on the wake of Nightwish, Edenbridge, After Forever.
