Eva Cassidy, cast most often as a blue-eyed soul diva and Chuck Brown confederate, showcased her “diversability” during a two-night, four-set stand at Blues Alley last week. The sessions, which were recorded, included enough jazz and R&B fare (Davenport/Cooley’s “Fever,” Irv Berlin’s “Cheek to Cheek”) to warrant placement in the city’s most celebrated and pricey jazz/R&B venue. But Cassidy also threw in interpretations of material made famous in different decades and genres by Buffy Sainte-Marie, Alex Chilton, Cyndi Lauper, and Sting. Up to this point, the habitual Wammie bestowee’s discography is limited to The Other Side, a 1992 collaboration with Brown, and an appearance last year on Pieces of a Dream’s Goodbye Manhattan. The latter gig brought Cassidy to the attention of the powers that be at Capitol Records, and she’s hoping to mine that vein for future major-label work. “I’ll be shopping these tapes around,” says Cassidy of the Blues Alley byproducts. Her go-go compadre didn’t make the scene, but Cassidy’s supporting cast for the gigs included Capitol Stepper Lenny Williams on piano, Chris Biondo on bass, Raice McLeod on drums, and Keith Grimes on guitar. If the majors don’t bite, look for Cassidy’s Live at Blues Alley to be released on Biondo’s label later this year.—Dave McKenna
