Instrumental music makes more room for the listener by opening up the palette—there are no lyrics that cue the listener how to feel. Whether this is true of extreme metal and the frequently unintelligible lyrics is arguable, though the titles and style of vocal delivery gives a pretty solid idea of what’s being communicated. This same openness can make describing or quantifying instrumental music difficult—a bit like translating poetry. Something inevitably gets lost. Some bands are, by their very nature, divisive. These bands are often idiosyncratic in their approach and tend to generate strong opinions; in short, you love ‘em or hate ‘em. Pryapisme, who have delivered another madcap romp with their new album, Diabolicus Felinae Pandemonium, are one of those bands.
