These are websites which will help you stay on top of the concert scene:
Ticketmaster.ca – The go to place to purchase tickets online for hundreds of concerts happening across North America. Most mainstream concerts will have their tickets sold on Ticket Master.
LiveNation.com – Another site which is vital to individuals who regularly want to attend concerts. Live Nation currently represents a ton of artists in the music industry and their website provides users information on purchasing tickets, and attending shows.
arts.nationalpost.com/tag/concert-reviews/ – In my personal opinion, The National Post has the best arts section of any newspaper in Canada, and therefore their insight on concerts performed throughout Canada is a useful tool in obtaining valued information.
http://concertsto.com/ – Displaying a list of all upcoming concerts reaching Toronto. A great guide to finding lower key shows mainstream outlets such as Ticket Master won’t have information on.
http://justshows.com/toronto/venues/ – A great list containing the location of all the concert venues in Toronto, several of which I actively work at.
