Glenn Branca was an American avant-garde composer, guitarist, and luthier. Known for his use of volume, alternative guitar tunings, repetition, droning, and the harmonic series, he was a driving force behind the genres of no wave, totalism and noise rock. Branca received a 2009 Foundation for Contemporary Arts Grants to Artists Award.

In music, a drone is a harmonic or monophonic effect or accompaniment where a note or chord is continuously sounded throughout most or all of a piece. A drone may also be any part of a musical instrument used to produce this effect; an archaic term for this is burden such as a "drone [pipe] of a bagpipe", the pedal point in an organ, or the lowest course of a lute. Α burden is also part of a song that is repeated at the end of each stanza, such as the chorus or refrain.
