Almost every CD that included the name of Vitalij Kuprij in line-up is interest object of mine. This time Ukrainian keymaster is a guest of Chilean guitar virtuoso. In my humble opinion, the most right qualification for a style that predominates on the CD is neoclassical shredding metal with orchestrations. Let's try to imagine yourself George Bellas' playing with symphonic elements added. That's the quintessence of Del Rio's music. Upon listening to such tracks like "Phantom Shadows", "Battlefields Of Glory", "Epic Dramatic For Electric Guitar & Keyboards" and album-crowning composition - "Flight Of The Bumblebee", we are entitled to call it "prestissimo music", that is music at a mad tempo indeed. Obviously, we must take peculiarity of the genre like shredding metal is into consideration, especially its characteristics: rapidity, precision, key and tempo turns, compositional complexity, and - in that case - even pompousness. Del Rio's guitar style can seem to be monotonous, so some listeners will regard it as a disadvantage. It's easy to tire the audience with such fast tempo with no common key and melodic changes at the same time. I admit that Chilean guitarist ia a representative of the most difficult kind of shredding metal in reception. It happens in such a way for two basic reasons. Firstly, the guitarist often breaks harmony principles (it means that listener has an impression of sonic chaos), and secondly - most tracks were composed on the basis of hardly-diverse repetitions. Surely, the alternation slow parts with fast ones is an advantage of the release. The album, as a whole, is very complex as regards instrumental: there is a typical Middle East instrument called sitar in "Oriental Fantasy"; we can hear baroque-inspired motifs in "Dreams Of Wisdom And Prophecy"; Felipe Porflitt's keyboard solos introduce necessary diversities; Vitalij Kuprij smuggles a progression here and there; Juan Francisco Rojas charmingly plays the recorder; and Pilar Aguilera along with Bernardo Rosselot(in "Nel Mezzo Del Cammir") beautifully perform their parts, being based on "Inferno" from "Divine Comedy" by Dante Alighieri. As we all know, we can like shredding metal or not, but can't disagree that its pefect command is a domain of not big, but elitist group of instrumentalists. It distinguished shredding metal over simple music subgenres. True enough, the listeners should possess the basics of the expertise to fully understand such album like "Journey Into The Fourth Dimension". Obviously, I am not thinking of our personal tastes, because that's another matter. If someone likes fast tempo, baroque reminiscences and majestic atmosphere, aforementioned album should meet all the requirements.
