Post Malone has cancelled the first few weeks of his "Big Ass Stadium Tour Part 2" with Jelly Roll, citing the need to complete his new album before the tour begins. The cancellation affects the first six regularly scheduled dates on the Live Nation-produced joint tour, which was set to begin on June 9 in Charlotte, NC. Malone has been promoting a 40-track album, titled "The Eternal Buzz," which is split into a two-part format and will have its 40 songs spread across two CDs. The delay comes amid reports of soft ticket sales for many dates, compared to last summer's tour which sold out every date and grossed a reported $170 million. Industry sources have suggested the album was already in the can, but Malone's announcement indicates it still has a way to go.
