This is one of those titles, I think, that will split the readership. It either does that magic thing for them, or doesn't. 
In essence, The Ballad of Buttery Cake Ass is a trip down memory lane, spurred on by nostalgia. It's the kind of fun and exciting that kept the younger versions of us bright-eyed. The discovery of music, the bands, the vibe. 
The book is, I completely agree, an ode to how things used to be - you went to a record store, you spent hours shifting through records, picking out the next album to play as your life's backing track. It's an ode to music that was... Because by heck, it was different back then, even some 20 years ago compared to most of the drivel that's being published nowadays, so I can stand by this book to keep the vibe alive. It's a title that anyone looking to chase that nostalgia should try. 

Personally, I'm afraid, the style of delivery did not work, so I called it a 'cut' at 21% in- I hadn't a clue what was going on most the time. 

It's chaotic and for many it's of the fun type, so don't try this book and judge for yourself!
