The overwhelming demand for tickets, which sparked the new additions, led Rodrigo's website to crash shortly after the tour was first announced.

Livvies can register for the Verified Fan presale hosted by Ticketmaster through September 17. Those who had already registered can update their date preferences to one of the new shows now.

The first presale, the American Express Early Access sale, will begin on September 19.

Rodrigo's 2022 SOUR Tour, which was held in smaller venues in North America and Europe, grossed $3 million.
