Not long after the Colombian band Aterciopelados released its 2001 album Gozo poderosa, singer and songwriter Andrea Echeverri took a break from the group to have a child. Her new, self-titled solo debut (Nacional Records) is a poetic but unflinching meditation on motherhood--this from a singer who previously scoffed at the notion of letting pregnancy distort her figure. The songs on this record, sung in Spanish, blur the lines between her own sexuality and her feelings for her daughter and her lover. On the catchy "A eme o" she sings "Since you were born I've become a better lover / It's as if you've unplugged my tubes," and on the tongue-in-cheek "Lactochampeta" she sexualizes lactation. The album was produced by her longtime Aterciopelados bandmate Hector Buitrago, and it reflects their taste for electronic flourishes and frothy pop melodies that draw on traditional Colombian music. Echeverri is touring with some of her old bandmates, and she's promised to play some Aterciopelados songs. El Guapo opens. Thu 3/10, 9 PM, House of Blues, 329 N.
