Harmonica player Gre?goire Maret, born in Geneva in Switzerland and harpist Edmar Castan?eda from Bogota in Colombia are two remarkable musicians. The strong musical affinity between them that comes across so vividly in "Harp vs. Harp" is no accident, not least because their backstories are so uncannily similar. Each of them came from his respective country as a callow teenager, and settled in New York. They have not merelysurvived, each individually, in the often unforgiving creative cauldron of New Yorks musical life; each has established a reputation at the absolute topn of the game, working on a regular, long-term basis with the best in the business.
