The Doors of the 21st Century
The Doors of the 21st Century Manzarek–Krieger is an American rock band formed by Ray Manzarek and Robby Krieger of The Doors in 2002. They have also been known as The Doors of the 21st Century, D21C, and Riders on the Storm, but have recently been using the moniker Manzarek–Krieger or Ray Manzarek and Robby Krieger of The Doors for legal reasons. They perform Doors material exclusively.

In 2002, Manzarek and Krieger reunited and produced a new version of The Doors, called The Doors of the 21st Century. The lineup was fronted by Ian Astbury of The Cult, with Angelo Barbera from Krieger's band on bass. 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. Densmore was initially replaced by Stewart Copeland of The Police but after Copeland broke his arm falling off a bicycle, the arrangement ended in mutual lawsuits, and he was replaced by Ty Dennis, who was the drummer with Krieger's band. Densmore subsequently claimed that he had in fact not been invited to take part in the reunion. The newly configured group performed on several TV shows including The Late Late Show with Craig Kilborn.

In February 2003, Densmore filed an injunction against his former band mates, 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.
