SOI is the musical vision of keyboardist Jonah Weingarten. This project came about during the fall of 2005, when Jonah felt it was time to establish himself as a creative force and a songwriter, in addition to a studio musician and live performer. The basic groundwork that became the foundation of the SOI sound was melodic, epic, occasionally progressive, and over the top Heavy Metal, strongly routed in the Swedish and Finnish sound, with a touch of American style riffing. Influences ranging from Soilwork, Iced Earth, Edge of Sanity, Arch Enemy, Children of Bodom, and of course Pyramaze can be heard.

This music embodies many of my early musical influences. It is really more a tribute than anything else. I combine my own style of songwriting with the melodic qualities of many of my favorite bands from Sweden and Finland.
