John Saavedra channels the spirit of Django Reinhardt into an energetic, New Orleans-inflected guitar sound that propels the swing music sound into this century just as it propels the dancers to the floor. Along with singer Giselle Anguizola, Saavedra leads the rotating cast of characters that is The New Orleans Swinging Gypsies, who can be heard at clubs across the Crescent City. Saavedra was featured in the hit show “NCIS: New Orleans,” and his original work can also be heard on ESPN.
