The Mars Volta will release La Realidad de los Sueos, a box set anthology of all of their studio albums and EPs on vinyl, on April 23rd. In addition to 18 pieces of vinyl, it includes a photo book with new liner notes and two pins. The bands Omar Rodrguez-Lopz helped oversee the release with label Clouds Hill.

The Comatorium deep-dive also includes two previously unreleased songs from the album sessions: A Plague Upon Your Hissing Children, which has never come out despite lyrics and melodies from it appearing in their 2006 song Day of the Baphomets, and Eunuch Provocateur, which had previously come out in a different form on the 2002 EP Tremulant. These songs have been pressed to double-etched vinyl.

The rest of the contents include pressings of Tremulant (2002), De-Loused in the Comatorium (2003), Frances the Mute (2005), Amputechture (2006), The Bedlam in Goliath (2008), Octahedron (2009), and Nocturniquet (2012).
