Thanks for the anecdotes, TAC and El Barto (cool avatar by the way!).
So, Maiden will be in Argentina for the next few days. There is one TV show (LaViola) and one on-line radio (Vorterix) which usually get to interview big rock bands and broadcast their concerts (or at least some songs). In fact, the guy who created Vorterix (Mario Pergolini) interviewed John Petrucci and Jordan in 2014, and was in charge of bringing DT to Argentina for the first time, in 2005. Maiden is one of the most beloved bands in the country and with a huge fanbase (I think they are second to The Rolling Stones in terms of popularity), so it wouldn't surprise me if the TV or radio journalists get to interview the band and/or broadcast some parts of the concert (the one in Buenos Aires, most probably)
I'll keep my eyes and ears open, and if any of you are interested, I'll post whatever I can find.
PS with a spoiler: So far, they have been playing
"The Book Of Souls", which is my favourite song from the new album. I hope we get a live, good-quality recording of it (especially that instrumental part at the end
So cool!).
