Could the piece you're referring to be "Double Igor" related to "Igor" or more specifically to Stravinsky's "The Rite of Spring" or another composition? If it relates to multiple Igors, it might connect to "The Double Igor Stravinsky Canticles" or another similar title.

The mention of specific names might relate to a piece titled or involving "Double Igor," potentially a modern or contemporary work involving multiple composers or performers with the name Igor.

Given the mention of "Oliver Hunt, Igor Miller & Igor," I would suggest the piece could be related to or a work by Oliver Hunt, Igor Miller, or a collaboration involving another Igor. One notable example I was able to consider involves names within specific orchestral contexts.
