I f you are an artist hosting an Arthop. Make it more interesting by providing live music. Most musicians welcome the chance to perform. Choose some one who will enhance the atmosphere eg: A performer who can provide enjoyable background music and wont distact from your work. Also it should be affordable. I charge $20 for small venues such as coffee shops and $50 for large venues such as Art Galleries etc. Some musicians will be more expensive and others may even play for free. Also people tend to hang around longer when music is provided.
