Praised for his “fluid virtuosity” and “soulful melodies,” Los Angeles native Brook Speltz has been inspired since childhood by the long tradition of deep musical mastery of artists such as Jascha Heifetz, Pierre Fournier, and the Guarneri String Quartet. As of 2015, he is the new cellist of the internationally renowned Escher String Quartet and a season artist of the Chamber Music Society. He has performed as a soloist, chamber musician, and recitalist throughout the US, Canada, Latin America, Europe, and Asia. First Prize winner of the prestigious Ima Hogg Competition, he has performed with the Houston Symphony, Colorado Music Festival Orchestra, and International Contemporary Ensemble, and is a regular performer at England’s IMS Prussia Cove and on tour with Musicians from Marlboro.

He has also toured with the cello rock band Break of Reality, whose cover of music from Game of Thrones has received over 19 million views online.
