The Denver, Colorado band is heavy. Heavy as fuck. Somewhat metal, somewhat doom, and very Melvins heavy as fuck, to be exact. The main reference point is still Houdini and Stoner Witch, but seeing how I rate those albums higher than any of the others in the Melvins' discography, it's not a complaint. Curtains is broken into three acts, with the first two focusing on a more conventional sound and the third exploring the more sonically tweaked."
