Bands with great second albums

I may be wrong, but isn't Steely Dan's second LP COUNTDOWN....?
Many great choices here. Strange Days (already said) was the first that came to my mind. How about counting the Buckingham/Nicks era of Fleetwood Mac as a new one, and submitting Rumors, which came after their S/T LP.. (-:

Oooops
Yes, Countdown is second.
5 day posting penalty for me.
