Markus: Very interesting thread indeed.
I understand where you're coming from, but at the same time, I'm leaning towards the sentiment I seemed to grasp from Freddynl's comments.
There has to be an outlet for "our" generation, and that's not necessarily gonna be with 120 db causing your ears to bleed or stobes and spots blinding you as you try to have a quiet evening with your lady.
As to the presence of other musicians...guitar, bass, some light brass..whatever, I'd look forward to performing with other musicians at any time, however, and this is the case where I'm living, so it's not necessarily gonna apply to all...but these day's money's tight, that goes of course for the owners of the establishments where you're playing. Now personally, I just enjoy to play, jam whatever, but other musicians don't necessarily like the idea of setting up to play..drag along the amp, guitar, mic stand, cables, monitors, etc. unless they're going to be reasonably compensated for their effort, and that's where the money thing becomes an issue. You're not to liable to get three or four additional musicians willing to split an ever shrinking fee for a nights work. So that's, at least to me, why the single acts seem to be popping up more and more.
I jam regularly with a number of different and versatile musicians, and we have a great time...jamming...just foolin' around...improvising. But I can't ask them to bring their gear out to some place that not willing to pay a three or four piece group a reasonable amount for their efforts. The club owner's just can't afford it.
I use sequenced material in my solo gigs, so what..the audience that I play to appreciates the effort put in to creating a pleasant atmosphere and bringing back the songs as they remembered them.
Just my thots....
Enjoy your summer everyone.
