Caleborate‘s latest album Real Person is out now and this song, just like every song on that album is relatable to the bulk of listeners. “4 Willem” is a song he dedicated to producer Willem Ardui who produced this song. No, the producer’s not dead or anything, Caleb just felt like writing a song about the European producer whom he’s still never met. While in New York he got to shooting some visuals for the song which you can watch above.
