I am about 30% of the way through the Matter audiobook (no spoilers please) and was putting off listening to it for quite a while because Peter Kenny is the perfect narrator for the Culture and I was wary of switching to a different narrator. But Toby Longworth is actually great! His narrating voice is good and his rendition of certain characters like Ferbin and Holse are perfect and hilarious. I love the banter between these two. There is a lot of humour in this book.
Also, I don't know if this makes sense to anyone else, but whenever I read Banks writing a medieval or fantasy-adjacent story, I get a very similar feeling to reading Joe Abercrombie's The First Law. I don't know if I can point to anything specific that makes me feel this way. I think it's something about the tone and humor and writing style that's very similar. I got a very similar feeling while reading Inversions.
