Been a long time! But Alessia Cara with my tween and her friends at Warehouse Live downtown. It was before she got "famous." Have to admit, she was really good. It was the biggest crowd she had ever performed in front of (maybe 1200?), and she lost her cool and started crying when the crowd started singing, "Here," word for word with her. Very endearing!
Otherwise, I've seen over a hundred concerts in my lifetime. Not so much anymore other than taking kids.
