I'm looking for a Gigi's song!

[Wario]

I'm being present to a Gigi's concert last week.
He make a great song that I never heard before. I haven't recorded it but I only can describe it that it was a slow and powerful sound song, Lento Violento style of course.
And there was a word in the song that say TETRAEDRO.

Please anyone know the song title or something that link me to that song to listen it again?!

Thanks
