Described as an “exquisite virtuoso violinist” (Chicago Sun-Times) whose “playing possesses a deeply profound musical instinct” (The Classical Network) and a “cultivated artistic taste” (Kulturas Diena, Latvia), David Lisker has appeared as soloist, chamber musician, and orchestral performer in many of today’s most prestigious concert halls including New York’s Carnegie Hall, Avery Fisher Hall, Alice Tully Hall, and Merkin Hall, The Mann Auditorium in Israel, The Orange County Performing Arts Center in California, The National Arts Centre in Ottawa, and The Shanghai Theatre in China. Mr. Lisker has also performed on the live PBS television broadcast of “Live from Lincoln Center”, was featured on Bob Sherman’s “Young Artist Showcase” on WQXR in New York, and was the only violinist ever to appear on David Dubal’s “Piano Matters” on WWFM Radio.

Mr. Lisker received his Bachelor of Music degree from the Manhattan School of Music where he studied with Pinchas Zukerman and Patinka Kopec, and went on to receive his Master of Music degree from the Juilliard School where he studied with Itzhak Perlman.


     Sarah Koo is known not only for her solo and chamber performances but also as an avid educator and outreach advocate. Ms. Koo graduated with her Master and Bachelor of Music degrees from The Juilliard School where she was the recipient of the William Schumann Award. In 2017, Ms. Koo was named one of the most 100 influential people in Orange County by the Orange County Register. Ms. Koo made her New York debut in a solo recital at Carnegie’s Weill Recital Hall as the youngest winner of the Artists International Competition.

     Ms. Koo served as the Assistant Principal Cellist of the Phoenix Symphony. Previous to her appointment with the Phoenix Symphony, she was touring Italy and Europe with the Symfonica Arturo Toscanini under the direction of Maestro Lorin Maazel. Ms. Koo, an outreach advocate, served as a teaching artist with the New York Philharmonic and brought music education to the public schools of New York. At the age of eighteen, Ms. Koo attended the Pacific Music Festival in Japan and was placed as the Assistant Principal Cellist.

    Ms. Koo appeared in the “Robb Report” magazine and a cover picture and story in the “Residential Systems” magazine for her interest in bringing classical music back to the home as a primary means of entertainment. Her avid desire to increase her classical music interest has led Ms. Koo to become involved in many outreach and educational organizations. Her involvement with the Community Service Fellowship at Juilliard, bringing performances to confined groups of people (e.g. nursing homes, cancer wards, etc.), has allowed her to encourage the genesis of similar programs by proposing ideas to different organizations throughout the United States.

    Ms. Koo can be heard on several different upcoming new release albums, including a collaboration with coloratura soprano Louise Toppin and an album of works written by John Christopher Dobrian. She recently was featured in four performances at the Barclay Theater, with a world-premier work by Alan Terricciano in collaboration with choreography by Vitor Luiz. Ms. Koo is currently the cello lecturer at the Herb Alpert School of Music at UCLA, the cello and chamber music lecturer at the University of California, Irvine, and on faculty at The Colburn School.
