In a new interview Chad Smith said that the band is "getting along great".
The 32-city global stadium trek kicks off in Spain.
It's the first tour since John Frusciante rejoined the band in 2019.
Major artists, songwriters, and producers like Shakira, Neil Young, RZA and Debbie Harry have sold part or all of their catalogs to Hipgnosis.
Smith was asked what fans can expect from the band in the coming months.
The supergroup has been doing covers on YouTube for the last year.
