Duality is a dual state or quality, and within mathematical systems a symmetry whereby a theorem remains valid if certain objects, relations or operations are interchanged. It also runs as both a feeling and realisation throughout the fourteen tracks included on the new album by Ferge X Fisherman. �Duality� is equal parts rap and jazz, contains electronically produced beats and live instrumentation, and is lyrically reflective yet totally unreserved. In regard to its lyrical content, �Duality� is ostensibly a self-portrait of a musician taking his first small steps onto the giant stages of the music industry. The record also features high-profile international guest stars such as Detroit rapper Black Milk and Japanese jazz trumpeter and Blue Note artist Takuya Kuroda (both on �Reality�), New Zealand soul singer Noah Slee (�Business�) and South African singer Hunter Rose (�Home�). With its unconventional sound, �Duality� is a unique statement of intent for the German hip hop scene and sets a standard for others to follow.
