Everything started with a message from MySpace to MySpace: "hey people, shall we do something together or what"?. That is how a promiscuous and tantric love story was forged, with a joint tour that has as its title Per principis elegants, in which both groups have worked a special repertoire for the occasion: ASSTRIO manufacture new bases for pieces of AT VERSARIS live, and the MCs elaborate new lyrics on instrumental themes by ASSTRIO.
