The overriding impression when listening to this album is of the consummate musicianship. Renato Rossert's piano and other keyboard work is superb, but then the other band members all contribute evenly. Even the drums are noticeably good. And the keyboards are sublime in places. Overall, the album would be a good addition to any Prog lover's collection.
Released at a time when Vittorio de Scalzi was not sure if he was able to use the New Trolls name, so the original LP was released simply as N.T. Atomic System. What happened was, shortly after the release of UT at the closing weeks of 1972, there was a split in the band. Vittorio de Scalzi wanted the band to go the prog rock route, which Nico di Palo wanted the band to go the hard rock direction. So New Trolls broke up, and di Palo went to form a group that was to be called Ibis (they had an album released in 1973 with a big question mark on the cover, which the name eludes me at the point)…
Once New Trolls ended up all the legal proceedings that led them to split into many different musical strands and other projects (Ibis, N.T. Atomic System, Tritons - real and fake ones -, Johnny from Tritons, and so on…), they reunited with “Concerto grosso n. 2”, published several reprints, live albums and compilations, and even entered the dance trend of the time with “Aldebaran” (1978), naturally followed by the Bee Gees-like “New Trolls” (1979), a.k.a. “La Barchetta” from its cover image. In 1981, with a line-up that reduced from 6 to 4 elements due to D’Adamo (bassist and lyricist) and Usai (keyboardist, who started an unsuccessful solo career), De Scalzi, Di Palo (the new bass player), Belloni (lead guitarist) and Belleno wrote “FS”, a back-to-the roots release, even in the shape of a concept album…
"Tempi Dispari" is a magical live album from 1974 by the Atomic System variation of The New Trolls, led by guitarist Vittorio De Scalzi after three members left to form what would end up being Ibis. De Scalzi is joined by future Nova keyboards player Renato Rosset, who influences this variation in a more jazzy oriented way than any other New Trolls incarnation. The band play here two side-long suites with side 1 really exploring the Jazz theme and side 2 including a theme from "Concerto Grosso 1" of excellent and innovative music with very heavy Miles Davis-like jazz prog rock influences.
