After a release on Liftoff Recordings, Kastra is back with his “Knockout” single through Safari Music. In bringing PKeys on board, a rap element is intertwined into the Melbourne bounce composition, which I’d love to see more of. Especially from Kastra, because his productions are impeccable every time he drops something. “Knockout” may be his most powerful yet, with an undeniable energy whose power will see that it takes hold of every listener it has. Grooves galore grace your ears after you hit play; even when it cuts to a half time beat, the music still moves you. Kastra is roaring loudly with his high-quality productions that keep coming and coming. If “Knockout” hit you in the right spots, then feel free to purchase the single through Beatport.
