I adore the self-titled debut and of course the
live beast/monster/classic Solar Music Live and also quite dig Rockpommel's Land. Jumbo was a bit of a letdown to me but Ballermann is the final essential
piece of the Grobschnitt puzzle. Eroc's first solo album entitled Eroc is also quite good for the most part as are Eroc Zwei, and Eroc 4. 3 doesn't do much for me.
