It's an unlikely pairing of instruments -- a harp and a vibraphone -- but the extraordinary duo of Charles Overton and Julian Loida make it work so well. The two are frequent collaborators, and they weave their ethereal sounds together in music that crosses and combines styles: ambient, jazz, world, classical, and much more. The streaming concert takes place from Futura Productions in Roslindale. This concert is produced using studio-quality production elements such as HD cameras, multiple viewing angles, and lighting in the partner venues.
