A mega concert is a large-scale music event featuring multiple artists or bands performing in front of a massive audience. These concerts often take place in stadiums or open-air venues and can attract thousands to even millions of fans. They are typically organized to celebrate a specific cause, promote an album, or showcase popular music genres. Mega concerts often include elaborate stage designs, advanced sound systems, and impressive light shows to enhance the audience's experience. Notable examples include events like Live Aid and Coachella, which have become iconic in the music industry for their scale and impact.
