It’s fairly easy to forget that one of the most important factors of a live performance that distinguishes it from a record is the sheer loudness of the music being played. Concertgoers far and wide are usually pretty good about remembering earplugs, as a result of this fact, and those that don’t can usually protect themselves with handy booths located within the walls of whatever theater they’re ready to get sonically disintegrated within. Generally, though, one can take a blast of churning riffs and thundering beats to the face for a few hours over the course of one evening, and come out relatively unscathed, albeit with their ears possibly ringing for a day or two afterwards. Thus, there lies an entire world of experimentation in the form of performing music at tremendously high levels of volume — although the songs can become almost painful in their intensity. Channel that sound into baleful, fearsome riffs, add a rhythm section that seeks to destroy bricks with its ferocity, and back it up with ludicrously powerful bass and howling, hellish vocals, and you’ll begin to glimpse what a set by the San Jose doom metal trio known as Sleep is like.
