I have noticed low turn out. It is especially concerning when bands come to a big city like L.A. and play a venue that holds 1000 and only 200 or under show up. It could be because the low or no advertising, timing, distance of the show for many, or cash. It seems like everyone (band and venue) depend only on internet advertising or websites to announce shows. Back in the day bands (major and local) would take out adds in the local entertainment paper. Now you just see listings, which are sometimes very small, for clubs with who is playing.
