Mistress 12.5 finds Anthony Rother’s ‘The World Needs You’ served three ways. The original is here, an airless techno jack that draws equally from ballroom and ghettotech. Next up is the acapella, a killer call that will cause scenes in the club if used wisely. Completing the trio is DVS1’s ‘No Bassline Edit’, a whirring L.I.E.S.-style delight. Mistress 12.5 rounds out with ‘Back Home’, a Rother original that is more complex than ‘The World Needs You’.
