X Japan

More or less unknown here but beyond huge in its home country—try 30 million records sold—X Japan is a virtuosic thrash-glam act with nearly three decades of stadium-rocking experience under its belt. Cheeseball theatrics are certainly in store, but metalheads are likely to raise an eyebrow or two at just how much heavier these guys are than their wussy American brothers-in-eyeliner. This gig is the group's first in the U.S. since 2010.
