I’ve had Mania for a long time. I have an EP/12” single too.
There is also 2011’s Remembrance which I don’t have.
Their first two albums are must owns. "Remembrances" is nice for background/behind the scenes info, like some rare/B-Sides compilations. Cool, but not necessary.
If you like them please check out "For Against". From Nebraska of all places! All of their albums are excellent!
