Ursula Knudson  of the Fishtank Ensemble  performs during the 17th Annual Santa Monica Festival at Clover Park on Saturday, May 10, 2008. Fishtank Ensemble is a band that offers a unique blend of Gypsy, Balkan, Flamenco, Klezmer and original tunes.  The arrangements are always surprising and include instruments from many countries such as violin, accordion, flamenco and gypsy jazz guitar, shamisen, bass, saw and voice.  From the smokey cafes of Bucharest to the Gypsy caravans of yesterday, Fishtank Ensemble evokes the spirit of a past age with the sounds of tomorrow.
