There was a time when live music was a big part of people's social lives. People went out and socialized, and wanted to be entertained. There was work for bands. There was money to be made, especially if you were willing to travel. I cut my teeth doing road work - approximately 2 1/2 years of playing 20-28 nights/month without stopping. The sets may have been the same, but every night was different. What sold you in a club on a 5 day stint was the variety and difference in each night. You still had to be good every night, but you had to be vibrant, as well.
In the late '70s, early '80s, playing for the door was the gamble and proof that the club's cash registers were ringing. Everyone benefitted. Now, it's merely a reason not to pay for entertainment, and you get what you pay for....nothing. It's the fault of so many bands for the current state of the business, not just the economy or clubs. If you can't engage your audience - STAY HOME.
