TR in Barcelona 2019 was not too bad, the end solo was ok, but way too short...
I heard three TR on that tour (barcelona, Valencia and Madrid), and all of them were just ok, in fact, in one moment or the others, he seemed like having trouble with the final solo, so when he dropped it, it made sense to me.
Yes, in retrospect it was a very bad idea to even contemplate playing TR in 2019. It sounded like a bad practice.
Maybe he thought in the start that he might be able to play it properly and after some performances he decided that it was better to stop playing it...
In my opinion, for fans, the version they were playing wasn't bad, actually I found them ok, but not special. It's obvious than them, specially him, considered the version not to be good enough.
