D.C.-area native Tori Amos is touring in support of her 10th studio album, Abnormally Attracted to Sin – and with 17 songs clocking in at a total of more than 72 minutes, it definitely is a long-player. The set finds the singing pop pianist in typical form: rotating between swampy and sour complicated tunes, and those that are sweet and searching, with gorgeous melodies. And all the while Amos often chews on her syllables, like a baby mimicking its mother. Did she just sing something about “sin”? Awww. Saturday, Aug. 1, at 8 p.m. D.A.R. Constitution Hall, 1776 D St. NW. Tickets are $45. Call 202-628-1776 or visit www.dar.org/conthall.
