Swedish Skull Crush

For the better part of two decades, Swedish death-metal band Opeth has been redefining its genre with audacious experiments in heaviness. Marrying the complex dynamics of '70s prog and elegiac folk atmospheres to extreme riff brutality, the group's music is as achingly beautiful as it is skull-pulverizing. The outfit's latest effort, Watershed, finds former Arch Enemy guitarist Fredrik Åkesson ably replacing axman Peter Lindgren as Opeth continues to develop its uniquely ominous sound. This bill, featuring support from Oakland's own power-trio juggernaut High on Fire and Georgia-based left-field sludgecore act Baroness, is sure to be packed with adventurous metalheads when Opeth headlines the Grand Ballroom at the Regency Center on Monday, Oct. 6, at 8 p.m. Tickets are $22.50; visit www.goldenvoice.com.
