Nothing wrong with a little artificial grazeland, of course, but the Roots are making tasty roughage that blooms into real songs, where raps wind around bass, drums, keys, and horns, and where instruments coil up to voice cadences‚Äîwhere music and lyrics meet and grow together naturally, not coincidentally. You can hear the Roots’ heart pump hardest when they pull off the things loops and samples cannot: just check the vocal/instrument interchanges of “Essaywhuman?!!!??!” or the left-turn instrumental digression midway through “Mellow My Man” to witness the living sounds of rap. The Roots’ Philadelphia-based groove collective build slick acid jazz playing around the smooth East Coast rhyming of A Tribe Called Quest and wild West Coast freestyling to create sounds as formless and fluid as jazz, but never unrecognizable as hip-hop. The music picks up where the mad scatting and melodic trills of L.A.’s defunct Freestyle Fellowship left off, and wakes up the tired hype of jazz/rap cross-polination to new possibilities. The roots of this kind of fusion have long been around, though perhaps these Roots are hope for a new dawning.
