I'll start, I guess.

An underrated poet that I really enjoy reading is Sandro Penna. Penna wrote a lot about shotas, youth and the quiet tragedy that comes with the ephemeral nature of such. His poems are typically very short (only a few lines long), but also very evocative. Some of them genuinely leave you stunned in ways you wouldn't expect. Very depressing at times, but generally nice. You can pretty easily find translated versions of his loveliest work in the collection "A Boy Asleep Under the Sun" online.
