The Itchyworms are a Filipino rock band whose music is primarily guitar-driven rock with pronounced 1960s and 1980s pop sensibilities and embellished with two or three-part vocal harmonies.
 The group made their name in the OPM (Original Pilipino Music) scene in 2006 with their sophomore effort "Noontime Show" with songs such as "Akin Ka Na Lang" and "Beer".
Sprechgesang (] , "spoken singing") and Sprechstimme (] , "spoken voice") are expressionist vocal techniques between singing and speaking.
 Though sometimes used interchangeably, "Sprechgesang" is directly related to the operatic "recitative" manner of singing (in which pitches are sung, but the articulation is rapid and loose like speech), whereas "Sprechstimme" is closer to speech itself (because it does not emphasise any particular pitches).
Keith Waithe is a Guyana-born musician, composer and teacher who has been based in the United Kingdom since 1977.
 He is best known as a flautist and founder of the Macusi Players – a world music jazz band whose name derives from the indigenous Guyanese Macushi people – and has been "acknowledged as the best flute player that Guyana has ever produced".
 His musical style explores a fusion of jazz, classical, African, Caribbean, Asian and Western influences, and he has also developed a technique he calls "vocal gymnastics", in which he uses the voice to reproduce percussive sounds.
 Music critic Kevin Le Gendre notes that Waithe "has single-mindedly pursued his own artistic agenda, developing a songbook that draws heavily on African-Caribbean and Asian folk traditions as well as jazz ingenuity in a manner not dissimilar to a large number of his forebears, of which Yusef Lateef is perhaps the most direct reference."
Screaming is an extended vocal technique that is mostly popular in "aggressive" styles of Western popular music such as extreme metal, hardcore punk, and industrial.
 In metal, the related death growl vocal technique is also popular.
 Intensity, pitch and other characteristics vary between different genres and different vocalists.

Strained tendon is a German band whose music and artwork is experimental.

Falsettone is a term used in modern Italian musicology to describe a vocal technique used by male opera singers in the past, in which the fluty sounds typical of falsetto singing are amplified by using the same singing technique used in the modal voice register.
 The result is a bright, powerful tone, often very high-pitched, although the sound is still different from and more feminine than what is produced by the modal voice.
 The term "falsettone" is also used for the mixed vocal register that can be achieved using this technique.
X Marks the Pedwalk (sometimes written as X-Marks the Pedwalk) is a German band whose styles range from post-industrial dance to electronic body music.
