skronk
n.— «The music touched on free jazz, especially when Krieger let forth some quick runs or hit those intense, dented notes aficionados refer to as “skronk.” He was a fiery presence onstage, often bending over an amp to produce feedback or furiously stomping on his pedals.» —“Lou Reed and Ulrich Krieger: ‘Unclassified’ at REDCAT” by Ann Powers Los Angeles Times Oct. 4, 2008.
