   Regardless of the venue, musicians usually perform on a stage. Concerts often require live event support with professional audio equipment.

Over the next few centuries, concerts began to gain larger audiences, and classical symphonies were very popular. Finally, after World War 2, these events changed into the modern concerts that take place today. An example of an early, post-WW2 concert is the Moondog Coronation B
