Mapping the evolutionary twists of Cave In is a tricky business. Active since 1995, early records experimented with chaotically corrosive trash metal before making way for the prog bombast of 2000’s Jupiter. By last year’s Tides Of Tomorrow EP, the excess flab had been trimmed, throwing their inherent gift for melody into sharper relief. Antenna compresses the formula further, fetching up crisp, anthemic crunch-rock several notches above the inexplicably popular likes of Bush or Papa Roach and suggesting a classic may soon be within reach.
