Thank you all for your wonderful reactions.
The whole show, actually a total of 3, are inspired by "la Leona", a very special and revolutionary guitar of the luthier Antonio de Torres Jurado, still a myth today. He is also responsible for other noteworthy guitars.
I don't know if the man is supposed to be a luthier but I love the question and will pass it along.
Carles Benavent (the alien
) is definitely a big influence! Modern flamenco has a debt with him. The guy playing the 5 string bass with frets I think is amazing. I have a video of his performance in the show if you are interested. He also just released a cd.
I´m still looking at the images from that day and will add more images if anything interesting pops up
