Concert promoter Live Nation is reigniting its amazing pre-summer discount ticket program, offering over 1 million tickets priced at $20 to some of its major summer tours.

The discount begins on May 1, which happens to be National Concert Day, a time for artists and fans to unite around their love of live music. Let's unite! Also, let's get cheap tickets.

AT&T customers get first access with a priority presale, beginning May 1 at 10 am; for details visit att.com/frontoftheline. For the rest of us schlubs, the general on-sale begins May 2 at 8 am. The sale runs for one week, through May 9.

There will be tickets for 50-plus tours and 1,000-plus shows at venues across the nation. This is the third year that Live Nation has offered the $20 deal.

Continuing the celebration of National Concert day, and launching the on-sale event, OneRepublic will perform live on NBC’s Today show on May 2. Definitely put that on your calendar.
