Yoko Ono: Season of Glass (1981)

After John Lennon's murder, Yoko took her anguish into the recording studio and emerged with this raw collection of songs. From the gunshots before the cut "No, No, No" to John's bloody glasses on the cover, this is harrowing stuff indeed. But it's surprisingly good, if only for the fact that the whole world was feeling similarly at the time. One of the most essential Yoko Ono releases, it's powerful and chilling. [source]

I am not a Yoko expert, but I think it's clear that this is one of her better records, along with her first Plastic Ono Band record.
