Rembrandt Pussyhorse, to me, is their lost classic. Doesn't get the love/attention that the more visceral Psychic Powerless and Locust Abortion get because it's more lowkey. But it should be held up as a classic rapeshit art rock album of the 80s.
It has the most "songs" from that period. Locust is 1/2 WTF noise things, Psychic is not that far from "rock" and Hairway is few songs.
Whirlling Hall of Knives is one of my favorites.
