Bands with great second albums


Bands that had a great second album. We all know the obvious ones Led Zeppelin, Hendrix, The Beatles. What are your votes for great second albums. Some of mine are:
Neil Young - Everybody Knows This Is Nowhere
Elvis Costello - This Years Model
Allman Brothers Band - 'Idlewild South'
Badfinger - No Dice

Yes- Indeed, Fragile is great... But their second album Time and a Word is a strong album. I really like their their first four, with Close to the Edge next. I am always engaged by their first two, and Time and a Word early press LP sounds darned good. Agree on Joni: Clouds, but I feel it is sandwiched between two better albums. 
Here are some more esoteric choices:

Gentle Giant, Acquiring the Taste
Ambrosia, Somewhere I've Never Traveled
PFM, Per un amico
Iceberg, Coses Nostres

Great times back in the day!

Schubert,

What was the Cleveland Symphony's second album? I don't think most people would be able to guess.
