Good read!
Yes, nowadays there are many artists that only focus on studio recording or composing stuff that is being played in movies, games, etc. Nothing wrong with that! But if you really want to be taken for serious as a band, or if you really want to "make" it, you have to go out and play your asses off... There's nothing better than a stunning and hypnotizing live performance, if you ask me! Of course playing live and performing is a learning process, and while starting out not everybody has that performing qualities or the emanation and attitude needed to be received well onstage. But one can learn (and learn from mistakes), and there will always be extraordinary performers out there who manage to really capture the audience AND deliver badass recordings.
