I think we all (well, most of us) agree that the most optimal playing experience is playing with other live players. Sadly, given the current economic clime, that is not always possible. For me (and ME ALONE), if I'm paying, I only want to see 'live' music. I don't even like seeing big stars performing to 'taped' backgrounds (although that is often the case). It's like the 'business' of music is more important than the 'art' of music. JMO.
