track, called "Breakn' a Sweat", was included on Skrillex's EP Bangarang. In 2013, the remaining members of the Doors recorded with rapper Tech N9ne for the song "Strange 2013", appearing on his album Something Else, which features new instrumentation by the band and samples of Morrison's vocals from the song "Strange Days". In their final collaboration before Manzarek's death, the three surviving Doors provided backing for poet Michael C. Ford's album Look Each Other in The Ears. On February 12, 2016, at The Fonda Theatre in Hollywood, Densmore and Krieger reunited for the first time in 15 years to perform in tribute to Manzarek and benefit Stand Up to Cancer. That day would have been Manzarek's 77th birthday. The night featured Exene Cervenka and John Doe of the band X, Rami Jaffee of the Foo Fighters, Stone Temple Pilots' Robert Deleo, Jane's Addiction's Stephen Perkins, Emily Armstrong of Dead Sara, Andrew Watt, among others. After the Doors After Morrison died in 1971, Densmore and Krieger went to London looking for a new lead singer. They formed the Butts Band in 1973 there, signing with Blue Thumb Records. They released an album titled Butts Band the same year, then disbanded in 1975 after a second album with Phil Chen on bass.

In 2002, the two together formed a new version of the Doors which they called the Doors of the 21st Century. Due to legal battles with Densmore and the Morrison estate over use of the Doors name, they changed their name several times and ultimately toured under the name "Manzarek–Krieger" or "Ray Manzarek and Robby Krieger of the Doors". The group toured extensively throughout their career. In July 2007, Densmore announced he would not reunite with the Doors unless Eddie Vedder of Pearl Jam was the lead singer. On May 20, 2013, Manzarek died at a hospital in Rosenheim, Germany, at the age of 74 due to complications related to bile duct cancer.
