[ THRU001 ] inZtance - This Is Where / What Must I Do? With the A side of Through Sounds debut release [ THRU 001 ] named "This Is Where", Through Sounds head honcho inZtance has gone deep into a Drum & Bass funk with a snappy repeating vocal hook that perfectly combines the gritty Bristol-sounding bass-lines and airy uplifting pads. Plenty of twists and turns in this unmissable one. AA. "What Must I Do?" is a dark, rolling monster-of-a-track, far from the optimistic vibes of its flipside "This Is Where". Perfectly placed growls and stabs alongside a thumping drum-line and a weighty sub-bass make this a dance floor heavyweight, destined to get the crowd moving, especially after the old school rave synths kick in on the second drop.
