What is striking, memorable, and sets this music apart is the originality and artistry of Eric the guitarist. There is some finger picking, some line weaving, chordal comps and a sound (must be an unamplified archtop semi-hollow) nicely percussive and punctuated.
It's a bit of a tour de force in plectorial artistry. You need to hear it. Eric Hofbauer has it all going on here.
