Coldplay have announced their Music of the Spheres World Tour.

The U.S. leg will be 11 stadium shows that run from April 23rd in Santa Clara, California through June 14th in Tampa. Fans can register now for a Ticketmaster Verified Fan pre-sale that will happen on October 20th. Tickets go on sale to the general public on October 22nd.

The small run of shows in the U.S. is part of the band’s plan to make their tours more environmentally friendly. They said in a statement, “We’ve spent the last two years consulting with environmental experts to make this tour as sustainable as possible, and, just as importantly, to harness the tour’s potential to push things forward. We won’t get everything right, but we’re committed to doing everything we can and sharing what we learn. It’s a work in progress and we’re really grateful for the help we’ve had so far.”
