In the late 60s jazz was at a turning point. Soul music had taken much of its black audience and rock's intellectualisation was eating up its support amongst college students. The usual story told is that jazz split between those who went out and those who tried to make people dance. The story is more nuanced, and 'If You're Not Part Of The Solution' tries to tell that story. It draws upon the melting pot of ideas that can be picked up in veteran Hammond player Johnny Smith's call for 'Black Feelings', or the cosmic wanderings of the obscure Philadelphia group Catalyst. Funk in all its forms can be found; be it the relentless bass rhythm of the title track, or the Miles Davis-influenced shifting groove of Johnny Lytle's 'Tawhid'. It was an exciting period and the music is caught up in that, but above all there is reverence for the greats such as Davis and John Coltrane who are the pillars of a newly confident African American culture. In 2019 the jazz revival spearheaded by Kamasi Washington in the USA and a host of young London based groups - Sons Of Kemet, Ezra Collective, etc - mix a variety of sounds to keep their music relevant for a younger generation. "If You're Not Part Of The Solution" explores where this happened first.
