Pounding dancefloors like a meat cleaver, the latest offering from Stakka finds hard techno sounds charging out of the speakers. Crisp and punchy one-two beats slam behind a nice female “I can feel it…” vocal on “Instransit,” which will bang in the clubs, but could use a few more surprises. Flip for “Junkyard,” which twists a variety of growling synths and bleepy noises into a swirling, rave-friendly miasma.
