Probably the best place to start if you're looking for an introduction to Michaux. The reason I'm saying so is this is a translation of a complete text, one from very early in his career. I may be wrong, but it could very well be the first book he published.
All told, it amounts to roughly 100 pages of prose poems, a handful of free verse and a very odd, very short one act play.
Michaux demands close attention and constant rereading. As you progress through the work you will find yourself gradually calibrating yourself to his interior world and the manner in which he represents it. This is highly claustrophobic, sometimes frenetic, sometimes explosive writing. Yes, there is some humor in this book, but to use a term like "Chaplinesque" to describe it is, in my reading of this work, not really on the mark. Sure, there's the feel of a bewildered character at the mercy of the modern world, but there's a lot more going on here beyond slapstick comedy and absurdist tropes. Some have called Michaux a modern mystic, one with no clear religious affiliation. There's something to that, as he himself claimed, some of his writings are "hygenic" and/or "exorcisms". Whatever is going on here, it is the result of a deep need to express the internal world through language. But this is neither a language of sense or nonsense. It moves back and forth, restlessly, relentlessly, and at times, painfully.
Beyond being all of the Michaux's work associated with Plume, it contains a bizarre 7 page chronology of the author's life, written by him in his late 50s. It's a slight contribution to his output, but like most anything he put his hand to, it's angular, unique and puzzling.
One last thought. If you're a fan of Beckett's mature output you really need to look at Michaux in general, once you've encountered him (along with some other French poets of the first half of the 20th century) Sam will not seem so sui generis.
