Grouper’s music is openly personal on record, but deadpan and noisy live. Be it the downtrodden whispers of 2008’s Dragging a Dead Deer Up a Hill or the solace of last year’s Ruins, Liz Harris dons her moniker with the intent to fill the air with smoke and draw shapes in its clouds. Instead of flowers and goofy grins, she sketches rotting corpses and beaches absent of life. Her new project, Helen, started with the intention of being a thrash band, but it quickly turned into something else entirely: a reverb-laden pop quartet. It seems Harris, the modest queen of reserved gloom, finally has reason to draw a smiley face. We just don’t know why.
