I mention the album a lot, but "Woods 5" by Woods Of Ypres. The album deals a lot with depression, but with a very strong message that you should appreciate people while they're still alive, not wait until they're dead to say how great they are and how much you appreciate them.

The band at the time were pretty unknown, they were actually booked to play a gig in my hometown at a 150 capacity venue and weren't even headlining. This album got a ton of great reviews and even won a Juno award (Canadian equivalent of a Grammy). But the main songwriter died a month before the album was released and he never got to see any of the praise and accolades for his work.
