After blogging about Bram I decided I should brush up on Tachisme. Which leads one to (among others) Wols.

(From above- Tachisme “is often considered to be the European equivalent to abstract expressionism, although there are stylistic differences (American abstract expressionism tended to be more “aggressively raw” than tachisme). It was part of a larger postwar movement known as Art Informel (or Informel), which abandoned geometric abstraction in favour of a more intuitive form of expression, similar to action painting.“)
