1973:
1.
Brian Eno -
Here Come the Warm Jets

A masterfully eclectic blend of glam and art rock. Some of it sounds like the future. This is in my top three albums ever.
2.
New York Dolls -
New York Dolls

This might be one of the most influential albums of all time. I think Morrissey claims that seeing the New York Dolls on the Old Grey Whistle Test had the biggest influence on his music of anything, and I believe it. This laid the groundwork for the style that punks would later adopt.
3.
****ney Rebel -
The Human Menagerie

One of the most underrated albums of the glam rock era. Steve Harley created a sound in 1974 that I think still sounds fresh today.
4.
Can -
Future Days

Perhaps Can's most beautiful recording. This is their "ambient record", which creates a peaceful and almost organic sound. "Moonshake" is also one of the greatest pop songs ever.
