What is "manzarek-krieger"

Manzarek–Krieger was an American rock band formed by two former members of The Doors, Ray Manzarek and Robby Krieger, in 2002. They were also known as The Doors of the 21st Century, D21C, and Riders on the Storm. They settled on using Manzarek–Krieger or Ray Manzarek and Robby Krieger of The Doors for legal reasons, after acrimonious debates and court battles between the two musicians and Doors co-songwriter / drummer John Densmore. They performed Doors material exclusively until the death of Manzarek in 2013.
