Kejuan Muchita (born May 21, 1974), better known by his stage name Havoc, is an American rapper and record producer. He was one half of the hip-hop duo Mobb Deep with Prodigy. 　　Havoc is from the Queensbridge, Queens; his mother is from Brooklyn. His brother Killa Black is deceased. Havoc is the lead producer of Mobb Deep, and has produced songs for MCs such as Eminem, Nas, Foxy Brown, Onyx, The Notorious B.I.G., Jadakiss, Styles P, Method Man, The Game, Puff Daddy, LL Cool J, La The Darkman, Rohff, Big Noyd, Termanology, Per Vers, O.G.C., Tragedy Khadafi, Capone-N-Noreaga, and his own partner Prodigy on his solo work. In the spring of 2005, Mobb Deep was signed to fellow Queens rapper 50 Cent's record label G-Unit Records. In late 2009, 50 Cent dropped the pair from the label. 　　Havoc is renowned among serious hip-hop fans as one of the prominent figures during the mid-1990s for his hard-hitting and stripped-down beats complementary to the RZA's work on Wu-Tang Clan projects. Popular music magazine Complex ranked Havoc among the top hip hop producers of 1995 after The Infamous.[2] Beattips.com ranked him as the 24th most influential beatmaker of all time[3] citing his dual abilities of rapping and producing. Following The Infamous, he tweaked his skills and transitioned to a more atmospheric production style that incorporated samples from classical music, most notably visible on the 1996 album Hell on Earth. As a rapper, he is known for his hardcore lyricism and consistent flow. He also contributed background vocals and a verse on Black Moon's debut album Enta da Stage in 1993.
