Since 2008 Jazzman's ‘Spiritual Jazz’ series has presented unlimited horizons; each album celebrates the rich tradition of African-American songs based on the belief in a higher force than oneself and has also focused on geographical areas, such as Europe or Japan, thus recognizing that these territories have immense cultural riches. Religions, like Islam, whose musical traditions have vivid Arabic and North African resonances, have also been highlighted. The stylistic range of all the above is wide. Yet historic record labels, from Blue Note and Impulse! to Prestige and Steeplechase, have also featured because their catalogues are musical treasure troves that could not be more relevant to Spiritual Jazz, even though they issued vast amounts of music between the late '30s and present day, that have not been confined to any one school. Spiritual Jazz 16 is a focus on Riverside and its associated sister labels.
