El-P, aka El Producto, is one of hip-hop's most obstinate and adventurous pioneers, combining a lo-fi old-school aesthetic with a progressive rock musician's inclination to push boundaries. He has never succumbed to the demands of corporate rap, instead choosing to pursue his own decidedly non-commercial direction. In the mid-'90s, he developed a strong reputation with the groundbreaking trio Company Flow, a band whose achievements include El-P-produced LP Funcrusher Plus on Rawkus Records, a label considered by many one of the best for intelligent hip-hop. Over the group's auspicious stint together, he proved he was himself capable of intense lyricism as well as sonic production so powerful it could stand on its own.
