Rounding out the most metal week ever, three more Ozzfest bands are mounting their own raiding party at Peabody’s. Taiwan’s Chthonic brings the blackness to a show headlined by death-metal icon Nile, which has carved out a niche by writing concept albums based on ancient Egyptian mythology. But the breakout for the bill is Atlanta’s white-hot Daath (pictured), a Roadrunner Records sextet that plays a smokin’ black-thrash hybrid. Former Chimaira drummer Kevin Talley makes the hooks hit hard, and if 1 in 10 bands could write a groove like “From the Blind,” metal never would have had to make a comeback in the first place.
