A roiling key soundscape gives way to plucked piano and big snare on Tennessee-based Magnum Dopus “8PM,” the opener on the band’s new full-length Suburbanova. I like the arpeggiating shimmery feel of the proceedings here, fueling Andrew McCarty’s strong vocal opening to the landscape. The song works easily well when it breaks and gets quieter, the shimmery key effect giving way to softer atmospheric sounds.
