in the 60s, some of the larger acts did full concept albums

Supremes - We Remember Sam Cooke
Four Tops - On Broadway
Marvin Gaye - tribute to Nat King Cole
Temps - in a mellow mood

Other acts really didn't do any [[aside from a few Xmas albums) - MRATV, Miracles, J5

so what concepts would you have like to see tackled and by which artists?

I was thinking maybe instead of the somewhat boring duet albums, the Sups and Tops could have done a concept around Godspell or J Christ Superstar
