"Strangiato" is a made-up word that the band used to describe a style of music that combined elements of classical, jazz, and progressive rock.
"La Villa" likely refers to a place, although it's not clear what specific place the title refers to.
So, the title "La Villa Strangiato" could be interpreted as something like "The Strange Villa" or "The Villa of Strange Music." It's intended to be evocative and mysterious, reflecting the music itself.
