Abbey and Helb have collected essays culled from an international group of authors from various disciplines. The common thread of the volume is aggressive music--broadly construed. The topics of the essays range from punk to hardcore to heavy metal to so-called Krishnacore. The contributors discuss the music in terms of emotional release, an aggressive way of separating groups/races, and a noisy indictment of all things corporate . . . [L]inked by thematically by aggression in music, essays included vary widely. . . .Overall, Abbey, Helb, and the rest of the contributors do a fine job of exposing important, under-appreciated elements of music on the margins of mainstream culture. Summing Up: Recommended. All readers.
