Siblings Jeff Bass and Mark Bass, professionally known as Bass Brothers, are known for their involvement in the career of "Rap God" rapper Eminem. The brothers no longer do significant production for the rapper but they still maintain a close relationship.

In a recent interview with Billboard, Jeff said nothing but good words about Eminem. The former even referred to the latter as "literally the Shakespeare of the art."

Jeff claimed that he never heard anything negative about the skills of Eminem in terms of his authenticity in the hip-hop game. The producer went on to say that the fact that the rapper is white does not really matter.

"He was hip-hop," Jeff said of Eminem. "Qe were all hip-hop. That's how we lived. It didn't matter what color you were."

In 2003, Jeff and Eminem won the Academy Award for Best Original Song for "Lose Yourself," which they co-wrote. It was from the soundtrack of the film "8 Mile," which was written by Scott Silver and directed by the late Curtis Hanson.

Eminem played the lead role Jimmy "B-Rabbit" Smith Jr., a young white rapper, in "8 Mile." The film was also the first feature film of "Captain America: Civil War" star Anthony Mackie.

Currently, Mackie is filming an untitled Detroit project written by Mark Boal and directed by Kathryn Bigelow. Detroit is the hometown of Eminem and the Bass Brothers.

Eminem was supposed to star in his second lead role in a film when he was offered the role of a boxer named Billy Hope in "Southpaw" but he eventually turned down the project. The role was played by Jake Gyllenhaal, whose recent film "Life" is set to have its world premiere on March 18 at South by Southwest, Variety reported.
