@jrp I would say the psychobilly fusion was best on Songs The Lord Taught Us. But it is hard for me to pick a fav. If pressed I'll pick Mystery Plane or Zombie Dance, even tho they a bit straightforward, stylistically, just for their roaring grit. But it has more to do with inventing the whole style combining rockabilly, punk, surf along with sort of fostering the whole band's approach.
