Singer-songwriter Jeremiah Tall recently shared “Graves,” the lead single from his forthcoming album Bare Bones, which is scheduled to arrive on October 11. A grim sonic swirl sets the tone. Unearthing a lively folk-blues stomp, the prediction of a zombie apocalypse is heeded. The end is near, and you’ve been warned. Hopefully it won’t come before Tall’s performance at Philly Music Fest on Saturday, September 27 at World Cafe Live.
