I agree they were a lot more talented than B2K and they could have gone on to do great things.
I actually still love both singles (Calling All Girls and Make It Up with Love) but haven't heard the whole ATL project album.

But looking back it was a time of boy bands with ridiculous names -
'b2k' - it's almost as if they knew they wouldn't last
and
'ATL' - so what if they're from Atlanta!
