Angus chose Perception as the title for this CD for two reasons. "I'm very interested in the way we humans perceive our world since our auditory, visual and olfactory senses are really quite limited," he explains. "I looked at different scientific discoveries about various imperfections in human physiology like blind spots, depth perception and optical illusions and applied these concepts to a musical setting by using displacements, metric modulations and polyrhythm not only as a basis for composition but also during improvisations." He also applied the concept of perception in a more fundamental way, namely how his music could be expressed and realized which is manifested in the album's instrumentation. "I wanted to explore as many different colors and sounds as possible, including non-standard combinations of instruments and ended up using 15 different musicians not only playing guitar, saxophone, piano, bass, drums and percussion but also a vocalist and a string quintet. I gave a lot of thought to the way I included improvisations on the album, because I feel composition is an area too often over-looked by jazz artists. To me it represents at least 50% - if not more - of any artistic statement I make so most of my compositions only include one soloist or a single solo section."
