Rex Marshall's existential industrial project Mattress mixes gritty and weary soul vocals. Marshall recently released a new recording, "Fuck the Future," on Modest Mouse frontman Isaac Brock's label, Glacial Pace, and it's a creepy, winding realm of sounds. Picking up on his years spent in Vegas, the now Portland-based artist has a dramatic and glitzy edge, like the tired singer in an old rundown casino or the pyromaniac running the laser light show. Opening this Sunday Session are NVRS LVRS and the recently debuted duo Reptaliens—the dreamy, explorative brainchild of Portland veterans Bambi and Cole. EMILY VANKOUGHNETT
