^{Malcolm McDowell at Rock & Shock 2009}

Starting tomorrow, metal worshipers will be descending on the House of Blues for two nights of "mind-throttling chasm-fording riff salad" (as Daniel Brockman so elegantly put it in last week's show preview) with High on Fire, Mastodon, and hometown-pride-instilling acts Converge, legendary hardcore heavies from Salem, MA, and Dethklok (the essentially fictional but wholly brutal cartoon band fronted by Berklee/Comedy Studio alum and Metalocalypse creator Brendon Small).
