I can't help feeling that a lot of this is Sport rather than music but I am also aware that the standard of these players in terms of core skills is a lot higher than it was in the past and that should be applauded. Aspiring to make a mark on youtube is pretty tragic, IMO, and playing other people's stuff ('bass covers' I think they call them) is a really odd way to spend your time.
I am aware, however, that this is like as not a generational thing and I, as a nearly 50 year old, am going to have a different perspective on the issue than 'the kids'. And that is as it should be. Better that they do this than smoke crack in a urine soaked stair well, I say
