I've never visited any concerts .I have hated our groups and singers. They can't sing at all. My favorite band is Queen. They are more than 40 years on stage. Those musicans are talanted. Especially I love the lead singer Freddie Mercury. Although he'd gone for good more than 20 years ago, but he never died in my mind. I know almost all songs those excelent musicans. Their concerts were and are great performances.
