Krumping is a street dance popularized in the United States, characterized by free, expressive, exaggerated, and highly energetic movement. The youths who started krumping saw the dance as a way for them to escape gang life and "to release anger, aggression and frustration positively, in a non-violent way."
The root word "Krump" came from the lyrics of a song in the 1990s. It is sometimes spelled K.R.U.M.P., which is a backronym for Kingdom Radically Uplifted Mighty Praise, presenting krumping as a faith-based artform. Krumping was created by two dancers: Ceasare "Tight Eyez" Willis and Jo'Artis "Big Mijo" Ratti in South Central, Los Angeles during the early 2000s.Clowning is the less aggressive predecessor to krumping and was created in 1992 by Thomas "Tommy the Clown" Johnson in Compton, California. In the 1990s, Johnson and his dancers, the Hip Hop Clowns, would paint their faces and perform clowning for children at birthday parties or for the general public at other functions as a form of entertainment. In contrast, krumping focuses on highly energetic battles and dramatic movements which Tommy describes as intense, fast-paced, and sharp.CBS News has compared the intensity within krumping to what rockers experience in a mosh pit. "If movement were words, krumping would be a poetry slam." Krumping was not directly created by Tommy the Clown; however, krumping did grow out of clowning. Ceasare Willis and Jo'Artis Ratti were both originally clown dancers for Johnson but their dancing was considered too "rugged" and "raw" for clowning so they eventually broke away and developed their own style. This style is now known as krumping. Johnson eventually opened a clown dancing academy and started the Battle Zone competition at the Great Western Forum where krump crews and clown crews could come together and battle each other in front of an audience of their peers.
"Expression is a must in krump because krump is expression. You have to let people feel what you're doing. You can't just come and get krump and your krump has no purpose."
David LaChapelle's documentary Rize explores the clowning and krumping subculture in Los Angeles. He says of the movement: "What Nirvana was to rock-and-roll in the early '90s is what these kids are to hip-hop. It's the alternative to the bling-bling, tie-in-with-a-designer corporate hip-hop thing." LaChapelle was first introduced to krump when he was directing Christina Aguilera's music video "Dirrty". After deciding to make a documentary about the dance, he started by making a short film titled Krumped. He screened this short at the 2004 Aspen Shortsfest and used the positive reaction from the film to gain more funding for a longer version. In 2005, this longer version was released as Rize and screened at the Sundance Film Festival, the Auckland International Film Festival, and several other film festivals outside the United States.
