Your eardrums will take a pounding, but that's what you metalheads want, right? So "Hell Awaits Metal Festival III" features 15 of the heaviest, hardest rocking, metal-piercing bands on the Islands. Ouch!

But it's not just a head-pounding wall of sound. It's also a chance to check out some of the newer bands that are trying to thrash out a place of their own in the Island musicscape.

Prepare to hear headliner 8mm Overdose, The Quintessentials, The Insurgents, Dark Harvest, Midnight Ablaze, Laissez Faire, Pacifica, Shadows of Sanctity, Haole Rot, Debauch, The Aftermath, Dagra, Augustine, Floodgate and Critical Mass — all in the low-ceilinged, pulsating, live-music haven that is Anna Bannana's.

It'll be loud, but it won't be so very nasty, so it's an all-ages concert, from 4 p.m. Saturday, ending at 1 a.m. Sunday. Admission is $8. www.underworldevents.com.
