'Spooky' is the perfect title for the A side, as unsettling piano and darkside strings build haunting vibes before the almighty drop - tough, energetic drums, speaker-worrying bass and a spectral synth line that walks through walls. 'Bittersweet' reinforces Kulture's connection to the classic dubstep sound - a sinister intro of menacing pads and echoing bleeps leads into a hard swung beat and slabs of sub-bass, laced with cooling organs and ongie-bongie percussion for heads in the know.
