That round-faced, barefoot lass with the corkscrew hair and the pouty lower lip, sitting at the piano and pounding a mournful tune full of poignant lyrics is not Tori Amos. It's Charlotte Martin or at least it was. The lugubrious introspective piano ballads with the spare arrangements have given way to more lushly arranged numbers and a heavy helping of synthesizers. "I grew up around orchestras," Martin, whose dad was an Eastern Illinois University music professor, says. "It's only natural I should be into synths." On Your Shore, her debut full-length, is the old Martin, who admits she bore a similarity to Amos. But Veins, her latest EP, is much more the Martin who has branched out from the chick pouring out her heart at the baby grand.
