Hi Percy. The parsing of 8D is convoluted but here goes. Split the answer into 4, 3, 2, 1. That gives you a genre of music that involves shouty TALKing, with an abbreviation for HARD inside, followed by a clump of EARTH, then a two-letter word that's in the clue (one of two times that Everyman does this in this week's puzzle!!), followed by the 'first' of EXHAUSTING (which seems pretty apt!)
