I went on quite an Italian Prog kick around 2 years ago, and discovered quite a few hidden gems. Of course, the more well known bands like PFM, Le Orme and Banco Del Mutuo Soccorso are all great. But I was able to discover quite a few more obscure bands as well as well. Such as

Alphataurus
Biglietto per l'inferno
Celeste
Corte dei Miracoli
Goblin
Quella Vecchia Locanda
Nuova Idea
Osanna
Il Rovescio Della Medaglia
I Giganti
Museo Rosenbach
Metamorfosi
Locanda Delle Fate
Il Balletto Di Bronzo
L'uovo Di Colombo
Murple

I'm sure there may be some I'm leaving out. But that's what I can remember for now.
