Normally with these blurbs, we focus on one band. But, I'm torn about this upcoming show at McCoy's in Olympia. I absolutely have to give shine to both Canadian sludge doom band Mendozza, and local up-and-comer metal monsters Bone Sickness. Let's start with Mendozza. These heavy hitters have been on the indie circuit now for six years. They chug and churn and hit below the belt with their arsenal of heady bass lines, rip-your-face vocals and guitar, and tattering drumbeats. Mendozza's drummer, Bina, says she's excited to play off their self-titled new album, specifically the 8-minute song, "Spirit Horse." "It's slow and Melvins-y, and super fun to play," she says. And Bone Sickness. Hot damn. These guys blister with eternal metal riffs and classic cookie monster vocals. They play dirty. They play intimate. And they play fucking loud. On local record label 20 Buck Spin, these guys are gaining momentum in the metal community. In 2010, Olympia ate 'em up when they opened for the Melvins at the Capitol Theater. Since then, Bone Sickness has continued their buzz with shows from here to Texas. Back at McCoy's for another night of head banging delight, Bone Sickness will not fail to deliver a raw performance.

MCCOY'S TAVERN, MENDOZZA, BONE SICKNESS, FRIDAY, APRIL 13, 8 P.M., $4, 418 FOURTH AVE., OLYMPIA, 360.352.0696
