There s nothing nice about Pearl s Anarchy Block unless an all black spike-riddled ear-splitting synthetic wood block tempts your musical soul. The newest addition to complement the mega-popular Anarchy Cowbell this percussion block will cut like an axe through the heaviest metal rhythm sections as a piercing alternative to a rim-shot. The swivel mount makes it extremely convenient to place virtually anywhere within your drum kit via any standard 3/8 percussion post. Obey no rules with the Pearl Anarchy Block.
