To celebrate the arrival of their second EP, Looking In (out now on Razor-N-Tape), Brooklyn band Underground System applies its fierce Afro-dance-punk sound across a heaving set of clubby jams. “A fitting compilation of recent favorites with some dance-floor energy to match,” band co-leader Domenica Fossati tells Apple Music on this 12th installment of In The Mix. “This mix was made on the run in London, and incorporates a heap of brand-new and recently released tunes by Underground System, artists we admire, and our extended Razor-N-Tape fam.”
