As Diamond Black Hearted Boy, Amobi became part of an underground scene of musicians using electronic production techniques to create a subgenre of sound collage dubbed "epic collage". "Nigerian Hair," a Diamond Black Hearted Boy track, appeared on Blasting Voices, a 2012 various-artists compilation featuring E+E (an alias of Elysia Crampton), James Ferraro, and Ryan Trecartin.
