'Concerto' is fantastic better than 'concert', simply because people who can even spell concerto let alone pay money to go and physically see one are well, wealthy. Classical Music is the upper end of town. This one has plenty of potential Kite26, the .online suffix is not a problem, it is merely a solution waiting to happen. Look into 'live online rehearsals', and you will see what I an alluding to.
