Shedneryan is a musical work for 60 minutes without interruption. A single composition with numerous changes of rhythms, sounds, sensations and atmospheres. This CD is an unrepeatable musical work probably because of the unique features. It distinguishes it from other disks of Roger. Having a mix for 60 minutes of music means having control of more than 750 tracks of musical instruments to manipulate at any time. Another difficulty lies in being able to make changes of styles, instruments, rhythm, atmospheres and still make it feel like the same composition. Each change should surprise but in the same time it has to work on the general perception of listeners in the same way during all the 60 minutes. On the production level, every change must preserve a technical characteristic of mastering, equaliation and dynamics. Any minimal change can produce a domino effect on the rest of the composition. Because of the special significance and personal meaning that this masterpiece represents there is no musical collaborations in Shedneryan. All - composition, performance and production is Roger’s work. The only external support is graphic art used for a cover, which is explained later.
