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.
