You're right...the busines has changed dramatically. For me, even though I use an arranager when necessary, it's still all about making music with other players. that interaction is irreplacable. I take less money to add a player or two.
Luckily, around here, horse farms and other places still have what I call "society" events, where bands are used and pay will.
Right now, I'm still going to play as many group jobs as possible, although, as we talked elsewhere, most are arranger, plus a sax/flute/percussionist and a guitar.
Believce it or not, but I'm starting some jobs with another keyboard player. We switch on real vibes...what a delight!
