Avant-garde destruction art flowed directly into mainstream rock performance

Evidence

Not all destruction art was scratched. The English band the Who—led by Gustav Metzger’s former Ealing Art School student Pete Townshend—did their trademark destruction thing at the Fillmore, ending their concert by trashing speakers, guitars, amps, and drums. — J. Hoberman, Everything Is Now, 1216

Categorization

• XREF: Supports the book’s core thesis that avant-garde ideas (Gustav Metzger auto-destructive art) permeated mass culture via artist-to-pop transmission — test case against claims that avant-garde energy died.
• ADDENDUM: Parallels the grafting idea — an avant-garde seed transplanted into the commercial rock infrastructure grows differently; relevant to how the scene becomes a market.
