Pedro Antonio Rojas, Jr. (born December 14, 1976), better known by his stage name Tonedeff, is an American rapper, producer, singer-songwriter and record executive.

Tonedeff first gained national recognition on the underground hip hop scene after winning a string of distinguished rap battles (i.e. "Braggin Rites"), opening shows for Common, Rahzel, The Beatnuts, Royce da 5'9", and Brand Nubian.

[1] He also appeared as a guest artist on several 12" releases, including the controversial KRS-One diss track "Clear Em Out" criticizing Nelly.

Born to a Cuban mother and a Colombian father in Newport News, Virginia, Tonedeff first began writing songs at the age of nine.

[5] Tonedeff formed a group named "The RBM Crew" in 1989 with three schoolmates shortly after relocating to Miami, Florida from Chicago and began recording and performing locally at talent shows and showcases.

[6] In 1993, The RBM Crew was offered a development deal by Warner Black Music and began recording the ultimately uncompleted Calligraphy.

After fielding offers from several major labels, Tonedeff decided instead to pursue a college degree in illustration and multimedia – taking a break from his music career until taking up recording of his debut solo project The Monotone EP during his time at Full Sail Center for the Recording Arts in Orlando, Florida.

HipHop DX gave Archetype an 8/10, praising Tonedeff's versatility and calling him "among the finest this genre has to offer.

"[10] In a review for IGN, Jim During seconded those sentiments, concluding "With one of the best flows in hip hop, Tondeff puts out a well-rounded debut.

He also executive produced many QN5 albums, including two critically acclaimed 2010 QN5 records, I F*cking Hate Rappers by PackFM and Robots & Dinosaurs by Kokayi.

According to the official description, "deals with the pressures and side-effects of anxiety, mortality and time-management over self-produced mid-tempo bounce tracks.

In 2002, Tonedeff joined with QN5 artists Substantial, PackFM, and Session to form Extended F@mm, which released the album Happy Fuck You Songs.

The group described the album as an exercise in "conceptual posse cuts" with songs ranging from the Tetris-themed "Line Drop" to bad cell phone connections in "Celly".

One of the more long-awaited and anticipated Tonedeff projects is a joint-collaboration with the hip hop producer Kno (of CunninLynguists) titled Chico & The Man.

[20] On this project, Kno is expected to handle the entirety of the production duties with Tonedeff to focus on the rapping portions.

Kno has said that the album has been pushed back to spring 2010 because of his participation in the CunninLynguists United States tour in late 2009 and because of paperwork for Tonedeff.

In early 2013, Peter Anthony Red made his next appearances, except this time as a director and executive producer for two cover songs by Danish artist Fjer, and her new debut EP, A New Start.

New episodes are generally released weekly, focusing on the lives of Tonedeff and PackFM, current events, the hip hop industry, and occasionally include special guests/friends such as Kno and Mr.

Support behind this endeavor grew very quickly, as Paste Magazine listed the show in their July "Ten Best Music Podcasts" article, and it was also featured in the iTunes New and Noteworthy section.
