Johann Kaspar Mertz was a Hungarian guitarist and composer born on August 17, 1806 and who died on October 14, 1856. His beautiful Elegie is the TOP 96 most recorded piece for classical guitar.

Of the group of most renowned and recorded contemporary Romantic guitarists (Napoléon Coste, Luigi Legnani, Giulio Regondi) Mertz is the only one that has achieved TOP 100 status. His own Fantaisie hongroise, Op. 65 is a close runner-up to Elegie as a favourite choice by recording artists.
