Do Mage Armor and Bladesinger stack?

I only have the 2024 PHB.   What is Bladesong?  What book is it?  Is this an item or a spell or a class feat?

It's a feature from Bladesinging, a Wizard subclass that appears in the Sword Coast Adventurer's Guide and Tasha's Cauldron of Everything.

 Also redone in the Forgotten Realms book released last year. But the legacy version is better.

If I am not missing anything, the legacy version is more MAD, gets light armor proficiency, and a worse Song of Victory feature so I don't see how.

Well, it didn't exist yet when I posted that, but the new version seems much better to me.
