the project uses grassroots ideology to grow and promote its mission to expose electroacoustic music. when the project receives more than 60 compositions of a particular theme or from a particular region, the project creates a themed mix to be represent that subsection of its submissions. the project has created many different mixes besides its main "international mix" which is a representative selection of the entire submissions made to the project for that year. alternate mixes created by the 60x60 project include: the athena mix, the canada mix, the untwelve mix, the presenters mix, the pacific rim mix,
