Probably seen about 100+ shows, most notable was Slipknot at the Molson amp last year, what a set and the charisma and stage presence is unbelievable, how Corey Taylor controls the crowd.
I've seen blink 182 4 times, the hip twice, the foo fighters (Amazing show) five finger death punch, and about 200 various metal bands most people have never heard of nor care to at different festivals throughout the years.
I've seen my favourite band In Flames from Sweden, going on 13 times since I started listening to them in grade 9, they are going on 24 years as a band and have 11 albums, they've gone from a very specific sound/genre they helped pioneer called melodic death metal to a lot more easy to listen to music in public... sometimes lol
