Sacramento sibling duo Blaq Tuxedo have penned hits for Chris Brown and Ty Dolla $ign; their fingerprints on those artists’ work are easier to dust for now that the Logan brothers have stepped out on their own. On ABA, they mix trap-music bass with tinkly toybox synthesizers and glue them together with their sticky, crooned Auto-Tuned hooks. It’s a weightless, effortless sound; their sweat-free cool is unmistakable in the suggestively undulating flute of “Stripper Friends” and the icy, one-finger synthesizer wiggle of “Charisma.”
