A taster’s menu of bite-sized songs and sonic vignettes, Yes Lawd is a feast for fans of R&B and hip-hop. Knxwledge’s unpredictable beats stoke the imaginative impulses of Anderson .Paak, whose raspy, melodic vocals on “Livvin” and “Suede” erase any division between rapping and singing. The collage of retro samples preserve an indie rap ethos, but with “Sidepiece” and “Link Up” the duo sculpts a new strain of sexy, smoked-out soul music.
