In a busy band scene saturated with a broad assortment of good (and terrible) cover bands, it’s hard for any local cover band or house act to really stand out. For local lady-rock group The Sirens, with their impressive, three-part vocal harmonies and range, it’s a piece of cake.

Comprised of three vocalists with multiple musical abilities and talents – Rachel Pardieck, Christi Smoak, and Fiona Phillips – The Sirens regularly deliver a delicate mix of classic rock and A.M. radio hits (Fleetwood Mac, Springsteen, Doors, Carole King), soul favorites (Otis Redding, Roberta Flack, Gloria Gaynor), and totally unexpected deep cuts (they’re the only band in town handling Bette Midler’s anthemic hit “The Rose”). Through the summer, they’ve performed almost weekly to an increasingly appreciative audience at the Map Room during one of the venue’s liveliest happy hours.

The trio tag-teams instruments and vocal duties throughout their sets. Pardieck handles the acoustic and electric guitar and bass while Smoak switches between congas and hand percussion to keyboards and Phillips plays guitar and keys.

Phillips and Smoak also play regularly together in local cover band The Cool, whose set features a variety of ’70s and ’80s radio hits and modern rock and Top 40 tunes and melodic originals. Both acts are pretty damn pro and can soothe the savage barfly within half a set. –T. Ballard Lesemann
