Born Jaime Meline, El-Producto or El-P is an underground hip-hop producer and rapper from New York City.

As a member of Company Flow, on the Rawkus Records label, he honed his production skills alongside DJ Mr. Len and Bigg Jus. His unique style helped Company Flow gain critical, then popular success, culminating in 1997 with Funcrusher Plus. Eventual differences between the group and Rawkus lead to El-P and Len leaving Rawkus in 2000.

El-P then decided to start his own record label, Definitive Jux. Of the many albums he has helped produce (most on Definitive Jux), the most influential and successful has been Cannibal Ox's only full-length album, The Cold Vein (2001). In 2002 he released his debut album, Fantastic Damage, which received critical acclaim. His follow-up, I'll Sleep When You're Dead, hit stores in March of 2007. It featured a wide range of artists, including The Mars Volta, Trent Reznor of Nine Inch Nails, and Cat Power. El-P has also contributed productions and guest raps to albums by DJ Krush, Aesop Rock, Murs, Cage, Mr. Lif, Prefuse 73, Del tha Funkee Homosapien, Mike Ladd, The High & Mighty, Aceyalone, and Alec Empire on the first Handsome Boy Modeling School album.

Cannibal Ox member Vordul Mega can be heard on "Linda Tripp", El-P's rebuttal to Sole's "Dear Elpee". He was also selected to work on Rage Against the Machine frontman Zack De La Rocha's solo album.
