At their first concert, the group announced that drummer John Densmore would not perform; it was later reported that he was unable to play because he suffered from tinnitus.

In February 2003, Densmore filed a motion seeking an injunction against his former bandmates, hoping to prevent them from using the name The Doors of the 21st Century.

His motion was initially denied in court and Ray Manzarek publicly stated that the invitation for Densmore to return to the group still stood.

It was reported that both Morrison's family and that of Pamela Courson had joined Densmore in seeking to prevent Manzarek and Krieger from using The Doors' name.

[1] In July 2005 Densmore and the Morrison estate won a permanent injunction,[1] causing the new band to switch to the name D21C.

The group then played under the name Riders on the Storm[1] after the title of a song by The Doors released in 1971 as the last track on the final Morrison-era album L.A. Woman.

"[2] Vedder previously performed three Doors songs with Manzarek, Krieger, and Densmore at the 1993 Rock and Roll Hall of Fame induction ceremony.

There is a keyboard on one side, a guitar on the other, drums in the middle, a bass line underneath that and the singer up front ... you can hear the words.

"[13] The band performed in Mexico, Bolivia, France, Israel, Russia, Italy, Czech Republic, the Netherlands, and Austria in 2011.

Forrest Penner subbed on guitar for all Mexico dates (Mexico City and Guadalajara) and La Paz, Bolivia when Robby fell ill. Ray's brother Rick Manczarek of Rick & the Ravens made several guest appearances on guitar throughout the tour.

Krieger said in a Billboard interview that he and Manzarek "talked about" recording some new music and even have songs they began when Astbury was working with them.

The Doors song "Wild Child" was also recorded by Astbury for the album with his band the Cult, along with Ray Manzarek.

The group played several new songs during their live shows that were intended for their unrecorded album, including "Cops Talk", "Forever", "Eagle in a Whirlwind", and "American Express".

[17][18][19] The songs for the album were written by Astbury, Michael McClure, Jim Carroll, John Doe, Henry Rollins and others, and was intended to be recorded in 2003–2004.
