Yeasayer + Day Wave

Making a sharp turn away from the upbeat electronica that populated its last two albums, Amen & Goodbye recasts Yeasayer as psych-rock evangelists. Thankfully, the group's output hasn't lost any of its gleefully bizarre charm, whether it's indulging in a woozy ode to chemistry or a bouncing tune about the Dead Sea Scrolls. ‘80s-tinged singer-songwriter Day Wave opens this official Lollapalooza aftershow.
