It's no secret that this album, recorded and released at the end of 1972 polarized the band. It brought a temporary end to New Trolls. The reason was guitarist Vittorio de Scalzi wanted to continue the eclectic route of New Trolls and the other guitarist (and vocalist) Nico di Palo favored a hard rock approach. And because of that, the group split, with Nico di Palo forming a group that would become Ibis, and Vittorio de Scalzi, with some legal problems wanting to continue the New Trolls name, had to continue on as N.T. Atomic System. You could already tell that all was not well with New Trolls with their previous album, Searching For a Land, which was a double album set, with the first disc a studio effort emphasizing the style Vittorio De Scalzi preferred, and the second disc a live disc of all-new material showing with Nico Di Palo preferred.
Many people regard "UT" as the high point of the Trolls career, others call it an uneven mess with some fantastic material and tedious material. It´scertainly a leap forward from their previous album, as it's a much more focused album.
The album is very well produced, and the hole album is a totally killer.
