Legacy of Vanilla Fudge

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" after the Doors song of the same name. 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-founder/drummer John Densmore. They performed Doors material exclusively until the death of Manzarek in 2013.

Hard rock or heavy rock is a heavier subgenre of rock music typified by vocals and electric guitars that are aggressive and distorted relative to traditional rock music. Hard rock began in the mid-1960s with the garage, psychedelic, and blues rock movements. Some of the earliest hard rock music was produced by the Kinks, the Who, the Yardbirds, the Rolling Stones, Cream, Vanilla Fudge, and the Jimi Hendrix Experience. In the late 1960s, bands such as Blue Cheer, the Jeff Beck Group, Iron Butterfly, Led Zeppelin, Creedence Clearwater Revival, Golden Earring, Steppenwolf, Grand Funk Railroad, Free, and Deep Purple also produced hard rock.
