Not A Number is the first instrumental solo project by the musician Sigh. With tons of influences, from seventies prog rock to some avant-garde metal, walking through post rock and math rock as well, Not A Number is an absolutely uncommon experiment where Sigh has put all the crazy ideas he could extract out of his mind.
