Not a book but I have only now come across this website -
https://www.compulsiononline.com/musicreviewtitlepage.htmA lot of reviews (of releases and gigs), interviews etc. mainly with old school industrial / experimental artists but also neofolk, some modern (ish) bands etc. Some content appears to be as old as from 80s/90s I think, but there are recent updates as well. Not easy to navigate because I guess design hasn't been updated in over 20 years and e.g. reviews are ordered alphabetically rather than chronologically but content is top notch. Apparently there was also a zine with three volumes - not sure when exactly but given volume one features Jhon Balance, it was quite some time ago...
