I listened to the first 4 or 5 hours of Finnegan's Wake. I've read like 12 pages of it before so I got considerably farther with the audio. I'm going to finish it despite only catching concepts here and there, it's still enjoyable to listen to. Apparently Joyce himself recommended the book be listened to rather than read.
Patrick Healy reads SO FAST which is double-edged. There's no lingering over anything, and no attempt to help the listener. On the other hand it's over in 35 hours!
The structure of the book strikes me as depicting mental contents as they are sifted and sorted in a sleeping mind. Where Ulysses was about the stream of waking consciousness, in all its wild discontinuity and randomness, Finnegan's Wake doesn't even have a stream, just snatches of content flying around at a level below discursive thought. It's an incredible thing to attempt to depict, if that's what he's doing.
I estimate I am missing close to 100% of the puns, portmanteaux & etc.
