At turns slacker, garage-y, with a dash of alt-country, Atlanta-based singer-songwriter Mattiel’s sound is unique. Initially signed to Burger Records, her most recent album Satis Factory is her first with ATO (home to Alabama Shakes and Old 97’s among many others). This move broadened her sound, outside the lo-fi, DIY sensibility of her self-titled debut and into a space that’s a bit more polished and assured, but still lovingly craggy. “Je Ne Me Connais Pas” channels the White Stripes while the heaviness of the guitars in “Keep the Change” is buoyed by a xylophone. Mattiel will be joined by the groovy Calvin Love, who has a strange, lounge lizard sort of charm that you definitely do not want to miss. by Jas Keimig
