Are you the type of person who enjoys wearing outfits festooned with inverted pentagrams and upside-down crosses? Who likes the idea of spending a midweek afternoon facing down 10 metal bands all trying to make your ears bleed? If so, the Summer Slaughter Tour might be your idea of heaven — or hell, since we're pretty sure that would be your afterlife preference. Morbid Angel is a legitimate legend these days, having been in the death metal game for more than 30 years, but the nine other bands here all have impressively rabid fanbases and — particularly in the case of Dying Fetus, Goatwhore, and Thy Art Is Murder — riffs to match. So all you pentagram-sporting metal fans are advised to take the afternoon off and miss nothing. This might be the heaviest lineup you'll see all year.
