Alternative metal
Alternative metal and nu metal bands sometimes employ screaming as well. Jonathan Davis screams in most of Korn's earlier songs. American nu metal band Otep frontwoman Otep Shamaya is also known for her usage of death growls as well as high pitch screaming. Serj Tankian occasionally performs both exhale and inhale screams, which are especially notable on System of a Down's first two albums. Limp Bizkit sometimes uses screamed vocals, especially on songs from their first album. Some bands combine screaming techniques with clean vocals to create a concrete sound with a noticeable change in tone, Chino Moreno of Deftones, who is famed for combining his high-pitched, aggressive screams with his calm and melodic singing, is a clear example of the concept alongside singers such as Corey Taylor of Slipknot.
