An army of bands has seized upon Biffy Clyro's sharply dynamic indie rock, filleting their sound for massive riffs (You Me At Six) and whispery, unsentimental melodies (Deaf Havana). Twin Atlantic and Marmozets have the Biffy prog pyrotechnics, Young Guns their mournful musical roar, and Lonely the Brave their razordrone guitar attack and skyborne howls.
