Louise Wener's Britpop memoir is 99p on Amazon Kindle this month. I've just picked it up, maybe you would like to as well. I don't know how many times I saw Sleeper play live but they seemed to be the division two band de jour at one point.
I got Phil Savidge's (from Pulp's press firm Savidge&Best) Britpop memoir recently, not read it yet.
Brett Anderson's follow-up book to his early years story, was a real disappointment. Lots of fancy adjectives and tortured descriptions, little in the way of anecdotes.
I know Jarvis' forthcoming book is specifically not a memoir but hopefully it'll be an interesting read/look at (think it will be heavy on visuals). Though I wonder if Covid has delayed it's publication given it is due to come out in a similar window to Beyond The Pale now that's been postponed (the Jarv Is record should have come out today alongside a Rough Trade performance/signing).
