George Macreyannes (Γιώργος Μακρυγιάννης) was a violinist active during the early part of the 20th century.  Some of these archival recordings are nearing 100 years old, so it is quite nice to get a glimpse of music that has such a remarkable history.  Respect to 1tracktape for a job well done in remastering and declicking these recordings.
