Mastodon

One of the biggest names in American metal, Atlanta's hardcore quartet grind out impressively convoluted, amped-up prog/metal noise more than a decade after starting out, here playing from their latest, rather accessible but still hard-hitting album – Once More 'Round the Sun. Hear their epic, groove-oriented riff-fests – which are edging ever closer to straight-up rock & roll territory – at this Tokyo leg of their Japan tour. Tickets go on general sale January 31.
