Obvious start, but....
'Our Band Could Be Your Life' by Michael Azerrad. So greatShame teh Husker Du entry skims quite a bit over their late period but i guess it fits with the more underground 80's vein of the book.
'Live Through This'- Everett True. Probably not popular on this forum (his fault of course), but i still love this. Even if he does only dedicate a paragraph to Buffalo Tom.
'English Folk Guiat Book 1'- Michael Raven. Mostly quality trad folk transcriptions, but the article on Nic Jones is ace.
