In terms of newly discoverable, I'm not sure, you're probably aware of most of these. Here are a few recommendations:
-
Symptoms (1974) from Mondo Macabro
-
Kamikaze '89 (1982), starring Rainer Werner Fassbinder, should be coming to blu-ray from Film Movement by the end of the year. The trailer is awesome:
-Cohen Media Group just released
The Films of Maurice Pialat Vol. 1, which includes Loulou (1980), The Mouth Agape (1974), Graduate First (1979), and a feature-length documentary on Pialat from 2007 called ‘Love Exists’. The first set is all four of those films for 30 bucks.
Under the Sun of Satan (1987) is also out, and
Van Gogh (1991) will be released in July.
-Cohen also just released Fellini’s
City of Women (1980)-Flicker Alley put out
Too Late for Tears (1949), a great underseen noir.
-Polanski’s
What? (1972) is now out on blu-ray from Severin
-Synapse released a 3-disc limited edition of Dario Argento’s
Tenebrae (1982) on blu-ray
And speaking of IV,
Candy (1968) is a real trip, and I’m pretty sure PT mentioned it as an influence on Inherent Vice at some point, which makes sense. The sense of humor is equally/similarly insane. Come to think of it the blonde girl in Dr. Blatnoyd's office also looks just like Ewa Aulin.

Oh and I haven't seen it, but
Belladonna of Sadness (1973) is coming to blu-ray in July from Cinelicious and seems like something you might like:
