Cautious Clay (a.k.a. Josh Karpeh) received an inimitable career boost after Taylor Swift’s 2019 song “London Boy” interpolated elements of his percolating R&B jam “Cold War.” The nod only cemented his snowballing momentum: Since the release of his 2018 debut EP, Blood Type, the Brooklyn-via-Cleveland musician has become known for rich, velvety vocal turns and immersive R&B production informed by his background playing flute, guitar, and sax. As a result, Cautious Clay songs are tinted by laidback jazz, hip-hop, and—in the case of “Swim Home,” a songwriting collaboration with John Mayer—cosmic soul.
