TLC

[P'NutButter]

I'd argue that their first 4 albums are the strongest run of any girl group, ever. It's just all quality.

 

[Coochi]

Crazy Sexy Cool and Fanmail have higher highs but 3D serves cute bop after cute bop with no stinkers (unlike the other two). A trilogy!

But... Fanmail is a flawless album?! What a record.
