Last year, the long-dormant Mars Volta seemed to be up to something. Socials teased something new, which turned out to be the career-spanning boxset La Realidad De Los Sueños. That was a limited release, but we also got a stream of unreleased material from their 2003 debut De-Loused In The Comatorium. After all that, things went quiet again — that is, until today, when the Mars Volta have returned with their first new song in over 10 years.
