Review: Want a non-stop drum and bass LP of 13 tear out bangers? Optiv & BTK offer no respite on Blackjack with its hi-octane fuel for the dancerfloor. Tracks like "Shredder", "Weapon Of Choice", "Dirt Box" and "Snake Bite" are as knees up as they sound, while "Ground Shaker", "Nemisis" and "That Sound" are as rolling as they are breakbeat. Featured MCs include Ryme Tyme waxing casual drawls over frenetic arrangements while Nuklear takes you down 'deeper deeper deeper'. No misfires here.
