For me, it was Fatboy Slim at the Warehouse in Toronto in 1999.
I actually did have a mobile phone at the time, but we're talking a Nokia 5190 brick with snake - no fancy camera phone haha
So, only great memories at this time - especially since both the Warehouse and the Guvernment closed and are now condos on Queen's Quay.
My first concert was The Wiggles (not the kids show, but an adult comedy band) in Bordeaux France. I was given tickets and was barely able to keep up with the satirical lyrics of the group.
Now a days I try to go to as many live events as I can in Toronto. There are so many small venues with great music for affordable ticket prices.
Are there any destinations you can suggest with some great live music? First thought that comes to mind are Irish Pubs...
