Exotica

There are no upcoming events right now.


The lovely Ms. Kostopoulos, whose ageless Mediterranean beauty perfectly complements a show incorporating Greek goddesses, set the mood with an excellent rendition of Dizzy Gillespie’s “A Night in Tunisia.”  The star makes extensive use of sensuality in her performance, often with the aid of Turkish finger cymbals, called zills. Kay Kostopoulos is a fine performer who will leave you enchanted and informed.  New York is lucky to have her.”... Andrew Poretz, Theater Pizzazz , NYC

 

Near the end of the set at Birdland, Kay Kostopoulos dressed as a member of a harem and sporting two pairs of finger cymbals soloed on "Boulevard Of Broken Dreams" was as close to finger cymbal virtuosity as I've ever heard (and if she wasn't also from the Bay Area, I'd claim this as an "only in New York" moment!)... Concert Reviews, Frontpage by Thomas Cunliffe.

 

Beautiful voice with a wide range... Ms. Kostopoulos is equally skilled on ballads and uptempo material...vocals that range from powerful to tender, a lot of spots for Jewkes to display his versatility and swinging ideas...Los Angeles Jazz Scene, Scott Yanow.

 

Wonderful lyrical imagery that transports the listener to another environment...Velvety vocal work, Billboard
