Beatles Peppers

With Revolver, the Beatles made the Great Leap Forward, reaching a previously unheard-of level of sophistication and fearless experimentation. Sgt. Pepper, in many ways, refines that breakthrough, as the Beatles consciously synthesized such disparate influences as psychedelia, art song, classical music, rock & roll, and music hall, often in the course of one song. Not once does the diversity seem forced – the genius of the record is how the vaudevillian "When I'm 64" seems like a logical extension of "Within You Without You" and how it provides a gateway to the chiming guitars of "Lovely Rita." There's no discounting the individual contributions of each member or their producer, George Martin, but the preponderance of whimsy and self-conscious art gives the impression that Paul McCartney is the leader of the Lonely Hearts Club Band.

The Red Hot Chili Peppers' eighth studio album finds the California foursome exploring the more melodic freeways of harmony and texture, contrasting the gritty, funky side streets of their early days. Luckily, with this more sophisticated sound, the Peppers have not sacrificed any of their trademark energy or passions for life, universal love, and (of course) lust. Although they recorded the spiky Abbey Road EP in 1988, this album actually sounds a lot closer to the Beatles' Abbey Road, with a little of Pet Sounds and elements of Phil Spector's lushest arrangements all distilled through the band's well-traveled funk-pop stylings…

Any discussion of the Top 100 '90s Rock Albums will have to include some grunge, and this one is no different.

Our list of the Top 100 '90s Rock Albums, presented in chronological order, takes in the rich diversity of the period.
