St. Louis native and Chicago resident Angel Olsen wowed critics (including yours truly) with last year's Half Way Home LP, on which the songwriter used her big, beautiful voice to reveal a startling set of tiny human truths. She has since gained considerable momentum: while Half Way Home saw the light of day thanks to the awesome-but-miniscule Asheville imprint Bathetic, its follow-up is set to be released on indie giant Jagjaguwar. Olsen has been debuting a few of the new tracks live over the past few months. "Forgiven/Forgotten," which she premiered at the Pitchfork Music Festival in July, showcased a psych-ier, more rocking version of her established '60s folk-influenced sound, thanks to her newly assembled backing band. Expect Tuesday's show to be a quieter, though no less impactful, affair.
