Concerts are live performances in front of the audience that may be performed by a single musician or by music ensembles, e.g., band, orchestra, and choir. Concerts can be performed in a variety of venues such as concert halls, arenas, parks, and sports stadiums. Shows often require live event support with professional audio equipment. On the other hand, music festivals are mostly done outdoor as these are massive events with many different performers with the events lasting for a couple of days.
