It's a long night at the bar
Without high quality entertainment this will come very apparent to your customers. When somebody leaves your bar, they are gone for the night.
If you book a traditional musical performance the promise is usually to play 2x 45 min sets. With that type of show the performance starts late and can easily be over before one o'clock. This leaves multiple hours in the early evening and late night when people don't have anything else but you and alcohol to enjoy. And let face it, you are probably pretty busy.
No matter how you slice it, no one man or bad can perform music for hours on end. This doesn't mean one man can't entertain for hours.
With my "X-Box" and unique experience I can deliver a high quality show that will bring a much needed change to many restraunts. Even your regulars will enjoy your venue more and share there experience on social media. This attracts more customers and helps to build your unique brand. What I have for you something innovative but still familiar enough to have a feeling of security. A combination of multiple bar classic.
Everything from classic rock to...... well mostly classic rock.
