The band's roots trace back to the late 1980s, when rapper/vocalist Toby McKeehan (tobyMac) started writing Christian hip hop under the moniker Caucatalk. While attending Liberty University, he formed dc Talk by joining up with vocalists Kevin Max Smith (Kevin Max) and Michael Tait. The name is short for Decent Christian Talk; the explanation can be found in the lyrics of the song "Time Ta Jam" which is on their self-titled debut album.

In 1989, the group released their self-titled debut album on ForeFront Records. They gained some crossover success when the "Heavenbound" music video received airplay on the BET network. Their follow-up album, Nu Thang (1990), also received attention for its hip hop/pop stylings (a la M.C. Hammer and Fresh Prince).



Their third release, 1992's Free at Last, was a tremendous success, producing six Christian radio hits. It was notable for its innovative blending of musical genres, combining hip hop with pop, rock, and gospel.

The group's best-known achievement, however, was their fourth album, 1995's Jesus Freak. This time, dc Talk had reinvented themselves as a pop-rock act, with little to no hip hop to be found. Now their music was much more similar to a fusion of the musical stylings of Nirvana, U2 or the Red Hot Chili Peppers than M.C. Hammer. The album also produced several radio hits. This album has been cited as one of the milestones in Christian music, as it appealed to a much wider audience and achieved much crossover success, having sold over 2 million copies. dc Talk capitalized on this phenomenal success by headlining a tour called "Welcome To The Freak Show", with live recordings later released on CD and VHS. They also wrote two books in collaboration with The Voice of the Martyrs, Jesus Freaks and Jesus Freaks II, each containing dozens of profiles of famous and lesser known Christians who died for their faith.

Their last album, Supernatural (1998), was not nearly the critical or commercial success as the previous two albums, but it also churned out its share of hits. The songs "Consume Me" & "My Friend (So Long)" received their fair share of radio play on Modern Rock, Contemporary Christian and Alternative outlets.

dc Talk also participated in Rocketown Records's Exodus album in 1998 with the song "My Will."

dc Talk has been awarded four Grammy Awards, as well as numerous Dove Awards. The group is notable for its stances against racism, as well as the uncompromised Christian message in its music. "We're very open about our Christian faith," says McKeehan, "but when we make our records we want to create a musical experience that anyone can immerse themselves in." But still, he says, "one of our goals is to encourage listeners to question themselves and to seek out truth."
