Back to the original post/question - very simply for me it was THE album that got me into U2, The Fly completely blew my head off. At a time when I 'knew' U2, had the Joshua Tree and Unforgettable Fire, that took it all to another level. Such a different sound. Not just to TJT but to EVERYTHING else around at the time, new, fresh, exciting. Bono's personas on the tour, Zooropa sweeping in as an icing on the cake - how can a band reinvent themselves like that?!. Boom. Cha. Just a phenomenal time for the band, and for me :-). I've seen them 20 times live...but never caught the Zoo! I am going to be ecstatic if they play an AB tour a la JT2017!!!
