Query: Bela Bartok: The 6 String Quartets - Emerson String Quartet

Bela Bartok: The 6 String Quartets - Emerson String Quartet is a 1988 Polydor recording starring the Emerson String Quartet. Anthony Burton and Eugene Drucker have written extensive and well-written music notes. Sound quality is truly outstanding and being a Deutsche Grammophon this is what one expects. An amazing performance from a very talented quartet. Not to be missed. Highly recommended indeed. 5/5.
