Here is a stunning history of Peruvian sound poems from 1972-2021. The album concentrates on material which has been recorded and edited, and yet showcases the compositional technique and sound organization across the spectrum of the discipline. It's an important and refreshing collection of 22 inherently absurd musical pieces, accompanied by seriously good liner notes.
Sound poetry can arguably be traced to oral poetry traditions, but I'm more inclined to believe it emerged from the Dadaist reaction to the horrific carnage of World War One, specifically through Richard Huelsenbeck and Tristan Tzara. Certainly it progressed through the 20th century parallel with the evolution of recording and editing technology. As mentioned, The Verbal Matter covers all the evolving styles, including montage, verbal dexterity, algorithms and computational parameters, and the use of AI.
