A buzzmaking production crew composed of Japanese-American teens Umi Takahashi and Yoko Watanabe, BenZel make their inaugural appearance in The DJBooth with a freshly-minted promotional single. On Semi Detached, the group showcase their talent for subtle mood-setting, crafting a beat that builds ever so slowly from a spare piano progression to a lush, yet ethereal alt-R&B groove. Singer/songwriter Cass Lowe, a DJBooth newcomer, handles vocal duties throughout the cut, which also boasts guest bars from an unusually subdued Chance the Rapper. Though unattached to any larger project, this low-key banger is sure to leave progressive-minded pop lovers hungry for more. If you fall into that category, you can keep it locked for more fresh tunes from this promising beat duo, as well as the latest from Chance and Lowe.
