With PFM, most fans of Italian prog rate Per Un Amico and Storia Di Minuto as their finest accomplishments. As Banco are a top 5 band for me, I'm going to suggest you give the following a good listen as well as the Museo Rosenbach track. If you can't get past the vocals on these after a few serious listens, i wouldn't waste any more time on Italian prog. as this is the pinnacle.
Museo Rosenbach - Zarusthstra
Whole of first side of the album of the same name. Reminds me a LOT of Gabriel era Genesis. I prefer this epic to Supper's Ready though.

Both from the self titled debut album (eaisly in my top 10, possibly top 5 albums if I ever do a top 50). The vocals on Metamorfosi don't kick in until after 8 minutes. The live version of Il Giardino.. is note perfect rendition of the album track, only the keyboards sound a bit different. Also worth listening to the album version. Yes are another top 5 band for me and I rate both of these on the same level as Awaken and Close to the Edge as far epics go. Most Banco fans also consider these as two of the definitive Banco tracks.

A beautiful little instrumental from their third album Io Sono Nato Libero.

A live version of the opening track on Io Sono... This version, once again is note perfect, but just the first 6 minutes or so of a 15 minute epic.
I could write a lot more about Banco, but I'll save your time reading and let you enjoy their music. If tis doesn't do it for you with Italian prog, nothing will. (Hopefully) ENJOY!
