The weather is warming up and festival season is just around the corner, making this the perfect time for National Concert Day to arrive in the US and Canada. The annual 'holiday' is back, and that means one thing: LiveNation's annual 'Kickoff the Summer' event is here again to celebrate the occasion.

For the third year in a row, the TicketMaster-affiliated company is giving up $20 tickets to 1,000 of its shows – and the list of applicable concerts is looking pretty amazing. From Future and Chris Brown to The Roots and Kings of Leon, the promotion is running until May 9, but the tickets will very likely sell out before then.

To claim, head over to LiveNation's website and search for your desired event, then select the "Kickoff to Summer Sale" option on the ticket page. The complete listing of applicable cities, dates, and shows can be found here.
