The album features Edan, Mr. Lif, Quantic, Percee P, MED, Bajka and members of the Dap Kings, Poets of Rhythm and El Michels Affair Earthology is the long awaited follow up to The Whitefield Brothers cult-classic In The Raw. While In The Raw's hypnotic, defiantly psychedelic funk music was grounded in the great musical traditions of both America and Africa, Earthology finds the Brothers infusing their funk (or, as the Brothers prefer it, "raw soul") with musical traditions that span the globe. To achieve the Earthology's unique sound, the Brothers employed an array of instruments and put in a dizzying amount of research: traveling the world, joining different bands and ethnic performing ensembles, amassing and absorbing field recordings, trawling used record bins for lost examples of global psychedelic-fusion, over a period spanning some fifteen years. Like In The Raw, Earthology is grounded by a "raw soul" band's building blocks: drums, guitar, bass, keys and horns, but it is augmented by such exotic instruments as gongs and flutes from Asia, xylophones and string instruments from Africa and Central American percussion instruments. The use of African poly rhythms now seems commonplace on a funk or psych album; Arabic rhythmical structures, African pentatonic scales and Oriental modes do not.
