Apocalyptica + Dir En Grey

Apocalyptica, the Finnish group that pretty much invented the genre of heavy metal played on cellos with its best-selling 1996 Metallica tribute, hits town in support of 7th Symphony, a typically bombastic new disc that features guest spots from Slayer's Dave Lombardo and Bush's (or Gwen Stefani's?) Gavin Rossdale. Redeeming the bill is Japanโ€™s Dir En Grey, which has jumped from experimental to pop to progressive rock since its 1997 formation. It seems the current lineup has settled on an extreme-metal foundation that still supports some rather sunny, goofy forays.
