The balance is off. Presumably the theorbo part is the accompaniment, the melodic part, played by the baroque guitar is barely audible when is should stand out.
My grandparents, (Mothers side) Iowa farmers never had electricity until they retired and moved into town, 1954. Oil lamps, wood burning heating and cooking stoves and a hand water pump outside the front door on the front porch. Entertainment was story telling and singing or reading the good book or other good books, sometimes aloud sometimes quite. We (mother & father) lived in the modern world, electricity, cars, gas etc, so it was like a trip into another country visiting that pair of grandparents. An old piano, quite out of tune sometimes, a fiddle and voices. Like another time, another world, another memory for an older 82 yr. old man today. A world without electricity did existed before my time on earth, back then things were...well slower. Before electricity most things were done by hand(s), feet and animals helping us. Today maybe just too easy, I'm not sure but it is sure different today than the early 1900's. WWII and the bomb change more than just that war. Good or bad, I just don't know!
Lovely! Among the many reasons why is the uplifting awakening of heart, spirit, and soul in the music of the Rebirth and of the Baroque, to hear it and even more importantly to see it performed on instruments of that time by musicians of the twenty-first century. It gives cause for optimism that what is good in our species may persevere. I note your acknowledgement of Luteduo. RU-vid, the Gutenberg Press of our Cyber Era introduced me to the magic of Anna and Anton some nine years ago.
