What is it about a concert that makes it truly memorable, is it the energy of the crowd, the performance of the artist, or the overall production value, and how do you think that compares to the rush of adrenaline you get from crossing the finish line at a big competition, do you think theres a similar feeling of euphoria that comes from a great concert, and if so, what do you think triggers that response, is it the music itself, the atmosphere, or something else entirely.
